Answer:
20 3/7
Step-by-step 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
· = · (you can divide 3 and 69 by 3)
· = <u> 11 x 13 </u> = 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
