Answer 2

Пошаговое объяснение:

3/8 * 9/11 = 27/88

5 3/5 * 1 4/21 = 28/5 * 25/21 = 4/1 * 5/3 = 20/3 = 6 2/3

1 1/15 * 5/16 = 16/15 * 5/16 = 1/3 * 1/1 = 1/3

22/35 * 21/44 = 1/5 * 3/2 = 3/10

9 3/7 * 1 3/11 = 66/7 * 14/11 = 6/1 * 2/1 = 12/1 = 12

7/11 * 2 5/14 = 7/11 * 33/14 = 1/1 * 3/2 = 3/2 = 1 1/2
