Adding fractions

[Georgia]

Who can help me? Right ive got 54 questions to do for tomorrow. Noone in the class no's how to do it even if the teacher goes over it hundreds of times. The teacher is rubbish!
Anyway i dont think im going to do the homework but i just need someone to explain how to do this -

Example -

4 1/5 + 2 2/5

I can do a bit of it but its hard to explain!!

Explanation cause ive got 54 to do! lol

[Kieeran]

hmm just adding? or multiplying too?

[Jase]

Did you have to simplify them as well?

[Georgia]

Im just adding them i have subtracting to do later but im not thinking bout that at the moment

Plus i dont have to simplify them

[Kieeran]

Ok adding is quite confusing

Examplle: 1 1/3 + 3 1/4 = 4 7/12

how?

MUltiply the denominators ( 3 x 4) = 12 thats your denominator


Then times Diagonally 1 x 4 then 1 x 3 but from \ like that s o it goes

1 1
\
3 4

Stay with me So1 x 4 and 1 x3 = 3 and 4 add them together you get 7 Simple as that

7/12 and with your whole number its 4 7/12 :)

Is that it?
We have to do somthing like this -

Example - 4 1/5 + 2 2/5 (Thats the question)
So its..

4 1/5 + 2 2/5 + 21/5 + 12/5 = 105/5 + 60/5 = 165/5 = 6 ? (somthing i dunno what it is over15) /15

So its like this -

4 1/5 + 2 2/5 = 4 x 5 + 1 = 21
2 x 5 + 2 = 12

12 x 5 = 60
105 x 5 = 105

105 + 60 = 165/5 = 6 ( 4+2) (then theres a number here but i dunno how to do it) /15

Try my way its ever so easier than tht i didnt understand it :P

[Georgia]

Try my way its ever so easier than tht i didnt understand it :P

I no there is more than 1 way how do it and we are allowed to do it the other way if we no how to but no one nos how to.
So my way + your way = should come to the same answer?

[Kieeran]

Yes post a question and wpost your answer doing YOUR way ill show my result

[Georgia]

I dotnr eally understand doing it my way so if i use your way for the first question it should be this -
(Question)4 1/5 + 2 2/5

(Answer) 6 11/15?

Edit - (Answer) 6 15/25

[Georgia]

Forget answer above i now no how to work it thanks kieeran
