Answer:

20 3/7

Explanation:

change each mixed number into an improper fraction

3 2/3 = (3 · 3 + 2) / 3 or 11/3

9 6/7 = (7 · 9 + 6) / 7 or 69/7

(11)/(3) ·
(69)/(7) =
(11)/(1) ·
(13)/(7) (you can divide 3 and 69 by 3)

(11)/(1) ·
(13)/(7) = 11 x 13 = 143/7

1 x 7

change back into mixed number form by dividing 143 by 7

you get 20 remainder 3, so 20 3/7
