Answer 1

Пошаговое объяснение:

3/7 * 4/5 = 12/35

5/9 * 2/5 = 1/9 * 2/1 = 2/9

6/7 * 21/22 = 3/1 * 3/11 = 9/11

(3/4)³ = 3/4 * 3/4 * 3/4 = 27/64

3/5 : 4/7 = 3/5 * 7/4 = 21/20 = 1 1/20

25/24 : 15/16 = 25/24 * 16/15 = 5/3 * 2/3 = 10/9 = 1 1/9

6/7 : 3 = 6/7 * 1/3 = 6/21 = 2/7

8 : 4/5 = 8 * 5/4 = 40/4 = 10
