Answer 2

Пошаговое объяснение:

1 5/6 * 4 2/5 = 11/6 * 22/5 = 11/3 * 11/5 = 121/15 = 8 1/15

3 1/2 * 1 3/4 = 7/2 * 7/4 = 49/8 = 6 1/8

4 2/7 * 2 1/3 = 30/7 * 7/3 = 10/1 * 1/1 = 10/1 = 10

1 1/3 * 1 3/8 = 4/3 * 11/8 = 1/3 * 11/2 = 11/6 = 1 5/6

5 2/7 * 2 6/11 = 37/7 * 28/11 = 37/1 * 4/11 = 148/11 = 13 5/11

10 2/5 * 4 3/8 = 52/5 * 35/8 = 13/1 * 7/2 = 91/2 = 45 1/2
