Пошаговое объяснение:

1) 5/8 : 7/12 = 5/8 * 12/7 = 5/2 * 3/7 = 15/14 = 1 1/14

2) 8/9 : 10/3 = 8/9 * 3/10 = 4/3 * 1/5 = 4/15

3) 2/3 : 5/12 = 2/3 * 12/5 = 2/1 * 4/5 = 8/5 = 1 3/5

4) 2/5 : 9/10 = 2/5 * 10/9 = 2/1 * 2/9 = 4/9

5) 9/16 : 3 = 9/16 * 1/3 = 3/16 * 1/1 = 3/16

6) 1 2/3 : 1 5/9 = 5/3 : 14/9 = 5/3 * 9/14 = 5/1 * 3/14 = 15/14 = 1 1/14

7) 8/25 : 0,6 = 8/25 : 6/10 = 8/25 * 10/6 = 4/5 * 2/3 = 8/15

8) 8 2/5 : 1 1/20 = 42/5 : 21/20 = 42/5 * 20/21 = 2/1 * 4/1 = 8/1 = 8
