Пошаговое объяснение:

2) = 1 : 1/2 = 1 * 2/1 = 2/1 = 2

3) = 1 : 5. 2/3 = 1 : 17/3 = 1 * 3/17 = 3/17

4) = 1 : 7/8 = 1 * 8/7 = 8/7 = 1. 1/7

5) = 1 : 9/10 = 1 * 10/9 = 10/9 = 1. 1/9

6) = 1 : 8/11 = 1 * 11/8 = 11/8 = 1. 3/8

2) = 5/12 : 2/3 = 5/12 * 3/2 = 15/24 = 5/8

3) = 4/9 : 2/3 = 4/9 * 3/2 = 12/18 = 2/3

4) = 8/15 : 4/5 = 8/15 * 5/4 = 40/60 = 2/3

5) = 2/5 : 6/25 = 2/5 * 25/6 = 50/30 = 5/3 = 1. 2/3

6) = 3/8 : 1/4 = 3/8 * 4/1 = 12/8 = 3/2 = 1. 1/2
