Is fraction necessary?
How will the world be without fractions?
Do you use fractions in your everyday routine?
What are the 4 basic operators?
Are these true or false? Explain.
1. 3/(7x) + 2/(7x) = 5 /(14x)

what is a fraction? well a fraction is a segment or portion of something, essentially a fraction is a number that represents part of a whole number, that whole number being 1. For example, in order to equally share a pizza between 8 people, the pizza would have to be cut into 8 equal parts, each part being a fraction i.e. 1/8. Or if the pizza was to be shared between 4 people,equally, each piece would have to be 1/4 or 2/8, which when reduced is the same as 1/4. Or two people would be 1/2 or 4/8 each or 16 people would be 1/16 each etc
ReplyDeletewhat is a fraction? a fraction can be seen as a number that can represent part of a whole number, or an expression which represents a quotient of two quantities....eg 2/3 etc.
ReplyDeletefractions are necessary to divide things equally.
the world would have no order without fractions....lets say we only had 1 political party to run trinidad the country may be one sided but there are two parties output add up which wrk to give one {WHOLE}!!!!!! output.
Fractions are very necessary, why? without fractions everything would have to be whole, meaning all measurements would have to be exact whole numbers, there would be no such thing as 1/2 an inch or 1/2 a litre. When measuring almost anything in existence, that can be measured it would almost always not be an exact metre, kilogram, Litre, foot etc etc. And thus would require the use of fractions. Without fractions, then we would have to do alot of guesswork which could and would lead to alot of incorrect measurements which in turn could lead to poor infrastructure, poorly manufactured cars, and more materials would be required to make it an exact metre or whatever the case may be and would thus be more costly. Even when making calculations, there would be no such thing as a decimal point, because all decimals are fractions.
ReplyDeleteyes i do use fractions in my everyday routine, and most of the time i do it subconsciously. For instance everyday when feeding my dogs i give them 3 and 1/2 cups each, without fractions i couldn't possibly do that.
ReplyDeleteThe four basic operators are simply:
ReplyDelete1) Addition '+'
2) Subtraction '-'
3) Multiplication 'x' or '*'
4) Division '/'
1. 3/(7x) + 2/(7x) = 5 /(14x)
ReplyDeleteFalse - because when adding two fractions of the same base or denominator (number at the bottom) only the numerators (the numbers at the top) are added and in this case both the numerators and the denominators are added so therefore this equations is incorrect
2. 3/(7x) + 2/(7x) = 5 /(7x)
True - since the only numbers added here are the numerators so therefore this equation is correct
3. 4/(9) = 4 x 1/9
True - in this case anything goes since it is multiplication, unlike the other 2 which were addition. In multiplication no matter what the denominator or numerator is, the question can be worked out by simply multiplying the numerators and denominators. In this example the numerators are 4 and 1, while the denominators are 1 and 9 (1 because 4 is the same as 4/1) and when multiplied the answer is simply 4/9, because 4x1=4 and 1x9=9
4. is also false since it is simply a blank space :)
ReplyDeletethe four basic operators are: addition, subtraction, division and multiplication. fractions are a part of everyday life, for example simply cutting up a piece of roti or a piece of bake. a fraction is an equal part of a whole. the world without fractions would be a world without sharing.
ReplyDelete3/(7) + 2/(7) = 5/(7) - simply add the numerator because the base is the same.
4/(9) = 4*1/9 - false, because it is less than a whole.
3/(7*) + 2/(7*) = 5 (14*)- false beacuse only the numerator is supposed to be added when you have the same denominator. the denominator was not supposed to be multiplied.
a fraction is a number which has a numerator and a denominator and a division sign... which means that the top number (the numerator) is divided by the bottom number (the denominator).
ReplyDeletefor the questions
ReplyDelete1) is false since the common denominator is 7x and the answer will be 5/7x.
2) is corrects using LCM you will get 2+3/7x will will equal to 5/7x/
3) the third one is correct since multiplying it will equal to 4*1/9 will be equivalent to 4/9.
the four basic operations are multiplication (*), division (/), addition (+) and subtraction(-).
ReplyDeleteMathematically a fraction is an expression that indicates the quotient of two quantities.
ReplyDeleteIn my opinion it can be considered to be
A disconnected piece; a fragment.
A small part; a bit: moved a fraction of a step.
I think that fractions are necessary because without them any system of measurement would not function at all.
ReplyDeleteYes I use fractions in my everyday routine
for example the amount of salt I put in my eggs,the amount of sugar I put into my tea and the list goes on simply to show how necessary fractions are.
The four basic operations are
ReplyDeleteaddition
subtraction
multiplication
division
A fraction is the ratio of two whole numbers, or to put it simply, one whole number divided by another whole number.Fractions is necessary because without it we will never find the exact value of anything.The world will be a mess without fraction with alot of stuff not workin.the 4 basic operators in maths are addition ,multiplcation, subtraction and division. 1.this is false because the LCM is 7x not 14x. 2. this is true. 3.this is true
ReplyDeletewhy is number 4 blank?
ReplyDeletein mathematical terms, a fraction is defined as the quotient of 2 integers, meaning that its the answer represents a piece of another whole number, eg. 1/4 (a quarter)
ReplyDeleteA fraction is not necessary. An answer can be stated as a decimal; for example, 1/4 is the same as 0.25, but a fraction makes it easier to state the value, and allows for ease of calculation
ReplyDeletehow would the world be without fractions....hmm...it would be 1/100 as interesting as it is right now...LOL!
ReplyDeleteYep, i use fractions in my everyday routine, namely time management, 1/2 hour to exercise, 3/4 hour to do homework...see...i use fractions
ReplyDeletethe 4 basic operators:
ReplyDelete1) Addition
2) Subtraction
3) Multiplication
4) Division
1. 3/(7x) + 2/(7x) = 5 /(14x) - FALSE!!!!!!!!!
ReplyDeleteOnly the numerator (number on top) is affected during an addition or subtraction of a fraction of same denominator (bottom number)
2. 3/(7x) + 2/(7x) = 5 /(7x) - TRUE
ReplyDeleteAs i stated before, during addition and subtraction, only the numerator is affected and in this equation it clearly follows this rule
3. 4/(9) = 4 x 1/9 - True
ReplyDeleteAny number multiplied by a fraction automatically gains the denominator (number on the bottom) with the exception that the number being multiplied has the same value as that of the denominator; eg. 10 x 1/10 (in this case the answer will be 1
what is fractions? a fraction is part of something whole. it is represented often by a number over a line an one that is under.the undermeath number represent how much to make to make a whole and the top represent how much is actually part of the whole. for eg. if there was 2/3 then it have two parts of the whole and three part would make a whole. fraction are necessary because it helps to provide equality, scales. yes i use fraction everyday and it is necessary
ReplyDeletethere would be no sharing. one and three is correct.
ReplyDeletea fraction is a part of a whole......fractions has both a numerator and a denominator, the top number and the bottom number respectively.
ReplyDeleteyes....fractions are necessary. without fractions the world would be weird.....very weird....for example the countries in the world would not be seperated but joined togeather.....uhhh!!!
ReplyDeleteyes.....we use fractions in our everyday lifes.....for example when making a sandwitch we dont use the whole bread but a fraction of the bread (ah talkin bout ah slice bread eh not hops...lol..)
ReplyDeleteFraction,,,,(this always makes a problem look scary)....hmmmmmm ....well...A fraction is the top number (called the numerator) divided by the bottom number (called the denominator). If we have a group of 40 people and 7 of them are under the age of 16, we can say the fraction of people in the group under the age of 18 is 7/40.
ReplyDeletethe four basic opperations are:
ReplyDeleteaddition (+)
subtraction (-)
division (/)
multiplication (*) or (x)
well in the morning i always use fractions for breakfast!!!! (no i don't eat it) =D.....wen mommy make a roti....i eat 1/2 =D....d roti was a whole.....and well we usually devide it in quarters....(4)...pieces...
ReplyDelete#1 is false since the bases are the same it would remain the same and only the top numbers or the numerator would be added
ReplyDeletefour basic operations...
ReplyDeleteaddition (+)
subtraction (-)
multiplication (x)
division (÷)
BASIC BASIC BASIC!!!!
#2 is true.....since the bases are the same it remains the same and only the numerator is added thus the answer.....
ReplyDelete#3 is true....
ReplyDeleteA fraction is a numerical value that represents part of a whole. It consists of a numerator and a denominator and can be added, subtracted, multiplied or divided.
ReplyDeleteYes u do use fractions in your everyday routines!. For example:by slicing a pizza for dinner, u need to cut it into fractions so that everyone will get a part of the whole (pizza).
ReplyDeletethe 4 basic operators: add, minus, multiply and divide
ReplyDeletenumber 2 is definately true, because u have 2 common denominators, therefore, u can just simply add the numerators to arrive at an ans.
ReplyDeleteno. 1 is false, u are not supposed to add the denominators. they are common, so u leave them as they are(7x)
ReplyDeleteThis comment has been removed by the author.
ReplyDeletehmmmm! the world without fractions. i would have to say that there will be no division amoung ourselves. We will not be able to arrive at an sample of anything, nor will we be able to share any part of a whole.
ReplyDeletethe basic operators are addition, subtraction, multiplication, and division
ReplyDeletea fraction is any number that can be used to represent a part of a whole. there is also the fraction called "decimal fracion", also known as um...decimal.
ReplyDeletea fraction is a number that is used to represtent a part of a whole and yes it is also known as a decimal fraction but most common called... decimal
ReplyDeleteFractions are a sort of measurement. Fractions are important because in reality if we choose to find the weight of an object for engineering purposes or other wise, and fractions are not involved...say we just estimate a whole number, then one cannot get a precise value to work with and therefore unecessary problems would arise. So in actual reality fractions are important
ReplyDeletea world without fractions, for example you would not be able to tell your friend to break a cookie in half n give you piece you could only tell them break it into and we all like equality when it comes to good things. A glass of water could never be expressed as "half full/ three-quaters full.... cant even say you want a quater roti" ...Fractions are part of our language and also mathematics
ReplyDeleteOf course i use fraction in my everyday routine..this morning i had a half a glass of juice......and my friend ate my whole sandwich
ReplyDeleteThe four basic operators cause increase or decrease to resulting numbers
ReplyDeleteThe four (4) basic operators are :
Addition (+)
Subtraction (-)
Multiplication (x)
Division (/
1) FALSE
ReplyDeleteReason being when the denominator (the number on the bottom) is the same,you add the 2 numerators (the number on top) ONLY
2)True
ReplyDeleteReason being only the numerators were added and not the denominators hence the ans is correct
3)False
Reason being 4/9 is a fraction, a part of a whole number and therefore cannot be 4(1/9) because that is a combination of a whole with a fraction
the 4 basic operators are:
ReplyDeletemultiplication x or *
addition +
subtraction -
division /
a fraction is a number less than 1 but greater than 0 and can be used to represent anything that has been broken up into smaller pieces or parts.
ReplyDeletea fraction is part of a whole!
ReplyDeleteThis comment has been removed by the author.
ReplyDelete4 basic operators
ReplyDeleteaddition (+)
subtraction (-)
multiplication (*)
division (/)
(1) that answer is wrong...in addition on fractions, if the denominator is the same, only the numerators are added an the denominator is left the same
ReplyDelete(2) that answer is right as the denominator was left the same an only the numerators were added
(3) 4/(9) = 4* 1/(9)
the number 4 can be stated as 4/1
4/1 * 1/9....the numerators are multiplied to give 4 an the denominators are multiplied to give 9
therefore the answer is 4/9 making this equation true
a fraction is a number that expresses part of a group. a fraction can be written in the form a/b where "a" is the numerator (number of parts chosen to be represented) an "b" is the denominator (the total number of parts)
ReplyDeletein my opinion fractions are necessary to an extent..wen we use many systems of measurement we never always have a whole answer but answers like 4 1/2 or 10 3/4 , which in my opinion again is still never accurate because one answer might be a little more than 10 3/4 but less than 11. a decimal now would be more accurate. nevertheless fractions are important in life
ReplyDeletethe four basic operations is addition(+), subtraction(-0),multipilication(*) and division(/).
ReplyDeleteWhat is a fraction?
ReplyDeleteA fraction is the top number (called the numerator) divided by the bottom number (called the denominator).
Is fraction necessary?
ReplyDeletefractions are very important and unavoidable.
Fractions are especially necessary in accurate measure in reality.
How will the world be without fractions?
ReplyDeletethe will be lots of chaos, because everything will be built on estimate or average, because there is no accuracy without fractions.
Do you use fractions in your everyday routine?
ReplyDeleteyes i do, throught the day. for example i use a fraction of a tube of toothpaste to brush my teeth.
What are the 4 basic operators?
ReplyDeletethe four basic operators are ....addition +.....subraction -.......multiplication x.... and division /...
a world withno fractions is a world that simply won't exist, there must be division in the world in some form or the other this could be a negative or a positive thing, a fraction of the world speaks english a fraction speaks french. a fraction is written like 3/6 and this also means 3 divided by 6.
ReplyDeletea world with no fractions mean we'll can't share a cake or we'll can't pay a taxi man a fraction off a hundred dollar bill if we don't have change we'll have to give him the whole hundred dollar bill.
the following are true
ReplyDelete3/7x + 2/7x = 5/7x
u are adding two fractions off the same whole,7x
4/9 = 4 x 1/9
the 4 basic operators are
ReplyDeleteaddition
division
multiplication
division
with these u can do anything
we say addmaths and some types of sums are hard
but they are these same operators that are placed in a simple order to solve that type of problem
i like to think to solve a problems or get to the root of a problem you apply the equation concept - do the opposite of what was done
if u added to get back to the start you divided
Its simple
But in real like its a confusing to apply the maths to what we did so how will we be able to undo it?
what do u all think
VERY SIMPLE
ReplyDeletea fraction is a representation of division and ratios .
we know that when talking about ratios we are talking about portions ,now e.g. 6/2,6 represents the value assigned to the whole ,while 2 represents the proportions which it is divided into.now if you take 1:2,this shows that what ever you have on the left is doubled on the right,so know ,knowing that 12/4 is the same as 6/3we see that fractions are most important because they not only represent division ,they also show the proportions by which quatities are related.
ARE FRACTIONS NECESSARY
ReplyDeleteobviously NOOOOOOO.
we did'nt have to call it fractions and we could have used any form of symbolism to represent the operations.what is necessary is that we as humans retain the abuility to reconize when something is bigger or smaller ,to understand proportins (division),simpley ,it is necessary to our survival that we can conceptualize these ideas and operations
mathematically a fraction is a ratio of 2 numbers. in a real life situation on the other hand a fraction may refer to a portion, a segment, a sum, a samlple etc.
ReplyDeletefractions are important because it gives an indication to the ratio in which things are distributed and how much of it is distributed
ReplyDeletethe answer to how fractions are used would summarize and reflect the idea how the world would be without fractions.
ReplyDeletefractions are used in management of time eg. how much time is used for rest, recreation, schooling etc. each one of these is done for a 'portion' of an average day. since a fraction is a ratio it can be found what most time is spent doing and inferences of personal preferences can be concluded by statistics such as these
so it goes to say the importance of fractions could reflect one's priorties it reflects what they consider important to them how they act toward it , how much time is dedicated toward it etc.
ReplyDeletethe four basic operators in mathematics are addition, multiplication , subtraction , division
ReplyDelete1) is false because there is already a lowest common denominator (L.C.M) which is 7x hence the syntax of this solution is incorrect the correct approach to this question is seen in part (2)
ReplyDelete3) 4/9 = 4 x 1/9 is true since an expanded version of this sum can be written as 4/1 x 1/9 which can be simplified to 4 x 1/9 or further simplified to 4/9
i would agree with all the explainations of what is fraction,they all are saying the same think which is identifying what is a fraction...
ReplyDeleteOf course fractions are necessary we use them in every aspect of our every day life and it's part of almost every thing,and again it is after all a mathematical statement which makes it not just necessary but very much important.
ReplyDeletei guess a world without fractions would be a place where there is no specific accuracy and every thing would be always less or more,that would mean there would be only whole numbers .........
ReplyDeleteyes i do use fractions in my every day routine,it is being used by people without there awareness,that is just to show how important it is to life on the whole.
ReplyDeletethe 4 basic operators are addition,subtraction,division and multiplication.
ReplyDeletewhat is a fraction? a fraction is a number that is not a hole number in other words a fraction is a number less than one such as 1/2 1/4 1/3 .............
ReplyDeletewhat is the four basic operators? the four basic operators are:(1)subtraction
ReplyDelete(2)addition
(3)devision
(4)multiplication
A fraction is the ratio of two whole numbers ,or to put it simply,one whole number divided by another whole number.
ReplyDeleteFraction is necessary because if not,life would have been very complicated.
ReplyDeleteThe 4 basic operators are: multiplication,division,addition and subtraction.
ReplyDeleteFractions consist of a denominator which is the bottom number which gives the number of parts in the whole as well as a numerator which is the top number that tells how many parts are showing.
ReplyDeletefractions are necessary they tell us about parts in relationship to a whole. That is, they give information about proportions or ratios.
ReplyDeleteWhat would our world be like without fractions? Our language would certainly change!
ReplyDeleteYou could never tell a friend to break a cookie in "half" to share with you. You could only tell them to break it into two pieces. A glass containing water could never be described as "half full." How could you describe this glass? There would be no such thing as "half past the hour" with timekeeping. You could never say you are "halfway" there when traveling.
Obviously, fractions are truly an important part of our language.
yea i do use fractions in my everyday routine, for instance when i eat roti on mornings. I do not eat ah whole 1 but a half or quarter of it!!
ReplyDeleteAS for the four basic operators they are simply:
ReplyDeleteaddition.
subtraction.
division.
multiplication.
A fraction can be described as somthing that contains a numerator and a denominator and is separated by a division slash (/) or whatever it is called. Both the numerator and denominator are intergers, for example 2/1 is a fraction as well as x/2 and f/d (assuming x,f,d represents intergers)
ReplyDeleteOFCOURSE fractions are necessary...everyday we use fractions in our daily life...when we eat food,we not always eat the entire pot. We eat a fraction of the food that is in the pot. When we organise our time tables,we use fractions to calculate how much time is spent doing specific tasks and studies, Miss used an example of a pizza in class already...Do u always go to pizza hut an order a 12 slice and eat the entire thing yourself...NO right,u use fractons to share it amongst you an your friends...YES fractions are very important!
ReplyDeleteHow will the world be without fractions you say...well,first of all...Will there even be a world to begin with? Our planet earth is basically made from fractions. A fraction of the earth is made of water,another is made up of soil, a fraction of the earth contains lava an other esential rocks and minerals.Even the air we breath is made up of fractions of Nitrogen,Oxygen,Argon,Carbon dioxid and other gases.Can imagine if the air was solely composed of carbon dioxide,then we would not be able to even breath...I think if the world could exsist without fractions we would be a WHOLE different species...hahahaha
ReplyDeleteYES i do use fractions in my everyday routine...my entire day is divided into fractions of activities such as eating,sleeping,studying,playing etc.
ReplyDeleteThe four basic operators are: subtraction,addition,division and multiplication
ReplyDeleteQuestion 1. is False...because...
ReplyDelete3/7x +2/7x= 5/7x
When dealing with the same (common) denominator i.e 7x, the answer is the sum of the numerators (3 and 2) over their common denominator.
Question 2. is True as i explained above...about the common denominator an so forth...i do not feel the need to repeat myself.
ReplyDeleteQuestion 3. is also True because 4 is a whole number and therefore it can me written like 4/1,so when u multiply both fractions
ReplyDeletei.e 4/1 X 1/9 = 4/9
Because the rules for multiplying fractions goes as follows:
(i)Multiply the numerators.
(ii)Multiply the denominators.
(iii)Simplify or reduce the resulting fraction, if possible.
uhm Question 4? miss wheres question 4?
ReplyDeleteThere isnt any question 4 is there?
awwwwww and i was enjoying this easy queezy fractions Topic..
A fraction is a portion or segment of a whole something. example let's say that we have 20 vests, and Samuel has 5 vests out of the 20 vests. this means that Samuel has 5/20.
ReplyDeleteYes! Fractions are necessary because if it did not exist then everything would have to be whole. Mesurements would have to be exact.whatever i have would be mine because i would not be able to share. Pieces would be inexistent.
ReplyDeleteThe world would not be as we know it if it were not for fractions. it would either be all water, land or air.everthing would have to be exact. nothing would be able to be done in pieces and it would be very difficult.
ReplyDeleteYes! I do use fractions everyday. when i am preparing for school, i first put on a fraction of my clothes at a time. I eat my breakfast piece by piece. I drink some of tea otherwise I would choke if I drank it all at the same time. ect. Fractions must be used everyday
ReplyDeleteThe four basic operators are:
ReplyDeletemultiply (*)
divide (/)
subtract (-)
add (+)
Question 1
ReplyDelete3/(7x)+ 2/(7x) = 5/(14x) => False
When adding fractions with the same denominator, the demoninator must remain the same
Question 2
ReplyDelete3/(7x) + 2/(7x) = 5/(7x) => True
Fractions with the same denominator when added the denominator remains the same.
Question 3
ReplyDelete4/9 = 4*1/9 => True
A dividor is the same as the inverse of that number being multipled. For example : 4/9 = 4 ninths. 4 * 1/9 = 4 ninths
answering what is a fraction
ReplyDeleteIn regular terms i think a fraction is part of a whole or infact part of anything which can be considered a whole.
Where as in mathimaticals term
ReplyDeleteI think that a fraction is the ratio of two whole numbers or a whole number divided by a whole number
Answering question is fractions necessary
ReplyDeleteI think that fraction are necessary because i our life everything deals with fractions. for exaample if we eat a slice of pizza that is fraction
In ones life we use time and we monitior time and when we record how long something takes to be done for eq 35min to was the car that 35mins is part of 1 hr or 60mins which is part of a day which is part of a week and a week is part of a month and so on.
ReplyDeleteAlso i think that with out fractions being present if we use sugar or peas we would not always use all of it .or all of everything we have then we would have to keep buy things .so it help use to conserve.
ReplyDeleteA really good example of why fracttions is important is when the government do a budget.For a budget is the use of fraction and is a step up which allow for the management of the countrys finances of else the country would not run smoothly.
ReplyDeleteIf my example of portraying how it is important please feel free to correct
a fraction is number used to represent a part or a segment of a hole.it also has a numerator and a denominator.
ReplyDeleteThe four basic operation of fraction are
ReplyDeleteaddition +
subtraction -
dividing /
multiplication *
Answering the last question
ReplyDelete3/(7x) + 2/(7x) = 5 /(14x)
1)is false since the common denominator is 7x and the answer will be 5/7x.This is because only the numerator (number on top) is affected during an addition of the fraction of same denominator
Answering Question (2)
ReplyDelete2)3/(7x) + 2/(7x) = 5 /(7x) - TRUE
during addition and subtraction, only the numerator is affected
aLSO FOR 2)
ReplyDeleteis corrects IF THE LCM process is used you will get 2+3/7x will will equal to 5/7x
Answer for 3)
ReplyDelete4/(9) = 4 x 1/9 - True
due n to any number which is multiplied by a fraction would gains the denominator (number on the bottom)
How to solve 3)
ReplyDeletetake 4 and change it to be stated as 4/1
4/1 * 1/9....then make sure numerators are multiplied
which would then give 4
an the denominators are multiplied to give 9
The answer would be 4/9 making this equation true
a fraction is part of a whole. whether it be a large or small part from that whole it is referred to as a fraction
ReplyDeleteyes fractions are necessary because without them parts of a whole something would not be available
ReplyDeleteThis comment has been removed by the author.
ReplyDeletewithout fracions present yhe world would be living on wholes. things would be wasted where little amounts or parts is/are required (this is where fractions come into play) and wholes would be used in excess
ReplyDeleteyes i use fractions in my everyday routine.
ReplyDeletethe four basic operators are-: addition (+) subtraction (-) multiplication (*) division (/)

ReplyDeletequestion 1
ReplyDelete3/(7x) + 2/(7x) = 5/(14x)
3/(7x) + 2/(7x)
find LCM which is 7x and the final answer works back to be 5/(7x)
therefore the answer is false
question 1
ReplyDelete3/(7x) + 2/(7x) = 5/(14x)
3/(7x) + 2/(7x)
find LCM which is 7x and the final answer works back to be 5/(7x)
the answre is true because the LCM is equal to 7x and the answer works matching the given one.
4/9 = 4 * 1/9
ReplyDelete4/1 * 1/9 = 4/9
this is true because when 4 is multplied to 1/9 it works out to be 4/9 which matches the given true/false question
Fraction - A way of writing numbers that are not whole numbers. The fraction is written like 1/2.
ReplyDeletea fraction is a number which has a numerator and a denominator and a division sign... which means that the top number (the numerator) is divided by the bottom number (the denominator).
ReplyDeleteThe four basic operators are simply:
ReplyDelete1) Addition '+'
2) Subtraction '-'
3) Multiplication 'x' or '*'
4) Division '/'
1) is false since the common denominator is 7x and the answer will be 5/7x.
ReplyDelete2) is corrects using LCM you will get 2+3/7x will will equal to 5/7x/
3) the third one is correct since multiplying it will equal to 4*1/9 will be equivalent to 4/9.
fractions are necessary since we use them in everyday life. it is vital in life because we do not always want a whole of some thing and it is easier to carry things in pieces rather than the whole .
ReplyDeletefractions are made up of pieces of the whole when all combine forms one.
yes i use fractions in my everyday routine
ReplyDelete1. 3/(7x) + 2/(7x) = 5 /(14x)
ReplyDeletethis is false because when adding two fractions of the same denominator only the numerators are added.
2. 3/(7x) + 2/(7x) = 5 /(7x)
ReplyDeletethis is true since the numerators only are added.
3. 4/(9) = 4 x 1/9
ReplyDeletethis is true since 4 * 1/9 will be the same as 1/9 +1/9+ 1/9+1/9= 4/9.
Fractions are considered necessary since without it everything would have to be whole, exact and therefore any system of measurement would not function.
ReplyDeleteThe four basic operators are:
ReplyDelete1) Addition
2) Subtraction
3) Division
4) Multiplication
Yes i use fractions in my everyday life.I eat my breakfast at a time,slowly,piece by piece. i drink a half glass of juice and i spend half of my school money everyday and save the other half.in my everyday actions i use fractions.
ReplyDelete1) 3/(7x) + 2/(7x) = 5 /(14x)
ReplyDeleteThis is false because when the denomenators are the same in a equation only the numerators are added and the demonenators remain the same.
2)3/(7x) + 2/(7x) = 5 /(7x)
ReplyDeletethe above equation is true.
An explaination for number to is the equation is true because when the bases are the same the demomenator remains the same and only the numerators are added.
ReplyDelete3) 4/(9) = 4 * 1/9
ReplyDeletethe above statement is true since 4* 1/9 is exactly the same as 1/9+1/9+1/9+1/9
fractions are used to indicate a specific value of something and if you would like to indicate how much of something is used up it would be easiest to give an exact value for example, you drank 1/2 of the soda. so fractions therefore come in handy..
ReplyDeletea fraction is a value that is considered to be part of a whole, especially a comparatively small part. it is also a ratio of two integers, the numerator and the denominator, usually written as the numerator above the denominator.
ReplyDeleteyes! fractions are definitely necessary and essential in our world.without fractions there will be no sharing, no equality ect.the world will be unequal if there was no use of fractions. fractions are used in everyday life and is an important,necessity of everyday living.
ReplyDeleteA fraction is a mathematical expression representing the division of one whole number by another.it is usually written as two numbers separated by a horizontal or diagonal line, fractions are also used to indicate a part of a whole number or a ratio between two numbers. The top number of a fraction is the numerator and the bottom number is the denominator.
ReplyDeletewell said XOXO.. great minds think alike. i was going to say that same thing..lol..
ReplyDeleteeveryday the use of fractions in my life is a must!! when i make breakfast i make a half cup of hot tea for the gas..lol.. and have 1/2 of an apple with and 1/8 of the loaf of bread. i also use 1/10 of money as funds for travelling to school on a daily basis.. it is therefore noted that the use of fractions in my life is evident..
ReplyDeletethe four basic operators are:-
ReplyDeleteaddition(+)
subtraction(-)
multiplication(x)
division(/)
without these operators you would not have an expression neither an equation.
1. 3/(7x) +2(7x)= 5/(14x)
ReplyDeleteThis equation is false
the equation in number 1 is false because since the two terms have the same denominator the resultant answer must also have this denominator so therefore the answer 5/(14x) is wrong
ReplyDelete2. 3/(7x) + 2/(7x) = 5/(7x)
ReplyDeleteThis equation is correct
the equation in number 2 is correct based on the fact the terms were evaluated properly with the proper addition of the numerators and the denominators and the resultant answer had the correct denominator and the proper addition of the numerator.
ReplyDelete3. 4/(9)= 4 x 1/9
ReplyDeleteThis equation is correct
the equation in question 3 is correct because the expression simply means that u have to multiply 1/9 four times so your resultant expression should be 1/9 x 1/9 x 1/9 x 1/9= 4/9.. so therefore the equation is relevant
ReplyDeleteyes fractions are important! then we wouldn't be able to share/ s;ice our birthday cake equally. or even our favourite milkshakes.
ReplyDeletein mathematical terms, a fraction is defined as the quotient of 2 integers, meaning that its the answer represents a piece of another whole number, eg. 1/4 (a quarter)
ReplyDeleteA fraction is not necessary. An answer can be stated as a decimal; for example, 1/4 is the same as 0.25, but a fraction makes it easier to state the value, and allows for ease of calculation
ReplyDeletehow would the world be without fractions....hmm...it would be 1/100 as interesting as it is right now...
ReplyDeleteYep, i use fractions in my everyday routine, namely time management, 1/2 hour to exercise, 3/4 hour to do homework...see...i use fractions
ReplyDeletethe 4 basic operators:
ReplyDelete1) Addition
2) Subtraction
3) Multiplication
4) Division
1. 3/(7x) + 2/(7x) = 5 /(14x) - FALSE!!!!!!!!!
ReplyDeleteOnly the numerator (number on top) is affected during an addition or subtraction of a fraction of same denominator (bottom number)
2. 3/(7x) + 2/(7x) = 5 /(7x) - TRUE
ReplyDeleteAs i stated before, during addition and subtraction, only the numerator is affected and in this equation it clearly follows this rule
3. 4/(9) = 4 x 1/9 - True
ReplyDeleteAny number multiplied by a fraction automatically gains the denominator (number on the bottom) with the exception that the number being multiplied has the same value as that of the denominator; eg. 10 x 1/10 (in this case the answer will be 1
a ratio of two intergers, the numerayor and the denominator. It is usually written one above the other and separated by a vinculum(horizontal bar)
ReplyDeleteFrations are important because everyhing does not come in whole,so we need fraction to represent the parts of a whole eg 1/2 of an orange.

ReplyDeletewow how will this world be without fraction i guess everything will be in wholes i really cant imagine... but i know for sure we need fractions
ReplyDeleteYes, i use fractions in my everyday routine.
ReplyDeleteThe four basic operations are :
ReplyDeleteAddition(+)
subtraction(-)
multiplication(*)
division(/)
3/(7x) + 2/(7x) = 5 /(14x)...false because when Adding fractions with the same denominator the numerators alone is added and here both numerators and denominators are added.
ReplyDelete3/(7x) + 2/(7x) = 5 /(7x)...true because when adding fractions with the same denominator the numerators alone are added.
4/(9) = 4 x 1/9...true because both are equal since 4/(9) is the same as 4 x 1/9(1/9 x 1/9 x 1/9 x 1/9).
a ratio of two intergers, the numerator and the denominator. It is usually written one above the other and separated by a vinculum(horizontal bar).it is a very improtant way to represent real life events
ReplyDeleteThe four basic operations in fraction and whole numbers are:
ReplyDeleteAddition(+)
subtraction(-)
multiplication(*)
division(/)
a fraction is the right combination of different elements to produce great things. e.g Me
ReplyDeletehow did man even know how to get fraction or was it just instinct that gave such wonderful by products (again Me).
ReplyDeleteA FRACTION IS PART OF A WHOLE.IT HAS A NUMERATOR, A DIVISION SIGN AND A DENOMINATOR.
ReplyDeleteFRACTIONS ARE NECESSARY BECAUSE IF THERE ARE NO FRACTIONS THINGS WILL BE VERY UNFAIR.
ReplyDeleteTHE WORLD WILL BE IN CHAOS WITHOUT FRACTIONS BECUSE IF THERE WERE NO FRACTIONS THERE WOULD BE NO BUSINESS IN THE SENSE THAT THERE WILL BE LOSSES RIGHT THROUGH
ReplyDeleteI DO USE FRACTIONS EVERYDAY BECAUSE I EAT QUATER OF A ROTI, I EXERCISE 2 HRS A DAY OF 24 HRS, I LOOK AT TELEVISION FOR 2 HRS OF 24 HRS AND SO FORTH
ReplyDeleteTHE FOUR BASIC OPERATIONS ARE:
ReplyDeleteaddition
subtraction
multilpication
division
question 1
ReplyDelete3/(7x)+2/(7x)=5/(14x)
