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

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?
