Answer 2

Пошаговое объяснение:

4/9 * 3/32 = 1/3 * 1/8 = 1/24

5/9 * 7/8 = 35/72

27/56 * 56/45 = 3/1 * 1/5 = 3/5

45/64 * 40/63 = 5/8 * 5/7 = 25/56

5 * 3/26 = 15/26

5/8 * 4 = 20/8 = 5/2 = 2 1/2

9/28 * 56 = 9/1 * 2 = 18/1 = 18

6 6/7 * 3/8 = 48/7 * 3/8 = 6/7 * 3/1 = 18/7 = 2 4/7

5 1/7 * 1 8/27 = 36/7 * 35/27 = 4/1 * 5/3 = 20/3 = 6 2/3

1 8/9 * 1 1/8 * 2 2/3 = 17/9 * 9/8 * 8/3 = 17/8 * 8/3 = 17/3 = 5 2/3
