Answer 1

Пошаговое объяснение:

14/15 : 7/10 = 14/15 * 10/7 = 2/3 * 2/1 = 4/3 = 1 1/3

14/15 : 21 = 14/15 * 1/21 = 2/15 * 1/3 = 2/45

14/15 : 1 5/7 = 14/15 : 12/7 = 14/15 * 7/12 = 7/15 * 7/6 = 49/90

14/15 : 2/7 = 14/15 * 7/2 = 7/15 * 7/1 = 49/15 = 3 4/15

7/10 : 3/8 = 7/10 * 8/3 = 7/5 * 4/3 = 28/15 = 1 13/15

21 : 3/8 = 21 * 8/3 = 7 * 8/1 = 56/1 = 56

1 5/7 : 3/8 = 12/7 * 8/3 = 4/7 * 8/1 = 32/7 = 4 4/7

2/7 : 3/8 = 2/7 * 8/3 = 16/21
