3/5 +8/35=?
First get a common denominator; in this case it's 35.
21/35 + 8/35 = 13/35
Try the others yourself. We'll be glad to check your answers.

7/9(13/18)
14/18(13/18)
27/18=3/2
is this correct?

(4)(3/2)
(8/2)(3/2)= 24/4
6 
Ms. Sue
Right! (4)(3/2) = 6

Ms. Sue
Right. And 3/2 = 1 1/2

deedee
ok I have 21(9)=12
wouldn't 21(21)=0 
Ms. Sue
Both are right! Great! :)

deedee
