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

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.

I know I put them wrong I mean 5/6 + 7/9
- math - Ms. Sue, Wednesday, October 20, 2010 at 10:04pm
5/6 = 15/18
7/9 = 14/18

which is 29/18 and so I change it to a mixed number?
- math - Ms. Sue, Wednesday, October 20, 2010 at 10:18pm
Right. And then simplify.
