Answer 1

Пошаговое объяснение:

4/9 : 2/5 = 4/9 * 5/2 = 20/18 = 10/9 = 1 1/9

2/3 : 13/24 = 2/3 * 24/13 = 2/1 * 8/13 = 16/13 = 1 3/13

2/9 : 4/3 = 2/9 * 3/4 = 6/36 = 1/6

36/49 : 6/7 = 36/49 * 7/6 = 6/7 * 1/1 = 6/7

15/16 : 3/10 = 15/16 * 10/3 = 5/8 * 5/1 = 25/8 = 3 1/8

4/35 : 8/5 = 4/35 * 5/8 = 1/7 * 1/2 = 1/14

7/12 : 21/16 = 7/12 * 16/21 = 1/3 * 4/3 = 4/9

3/10 : 7/100 = 3/10 * 100/7 = 3/1 * 10/7 = 30/7 = 4 2/7
