[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

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
