Okay 5/9 + 7/9
I know you change the denominator so
5/6 = 15/18 or 3/18
7/9 = 14/18 or 2/18
which one?

math 
Ms. Sue,
You only change the denominator when they are not the same. You don't need to change anything about those fractions  except simplify your answer.

Aly,
I know I put them wrong I mean 5/6 + 7/9

math 
Ms. Sue,
5/6 = 15/18
7/9 = 14/18 
math 
Aly,
which is 29/18 and so I change it to a mixed number?

math 
Ms. Sue,
Right. And then simplify.

math 
Aly,
is it 1 11/18???

math 
Ms. Sue,
Right. :)
