Ответ:

1) 3 : 1/9 = 3/1 / 1/9 = 3/1 * 9/1 = 27

2) 6: 1/11 = 6/1 : 1/11 = 6/1 * 11/1 = 66

3) 4: 3/8 = 4/1 : 3/8 = 4/1 * 8/3 = 32/3 = 10 2/3.

4) 5: 5/7 = 5/1 : 5/7 == 5/1 * 7/5 = 7

5) 2 1/7 : 15 = 2*7+1 / 7 : 15 = 15/7 : 15/1 = 15/7 * 1/15 = 15/105 = 1/7

6) 1 7/9 : 8 = 1*9+7 / 9 : 8 = 16/9 : 8/1 = 16/9 * 1/8 = 16/72 = 2/9

7) 4 1/2 : 6 = 4,5 : 6 = 0,75

8) 5 1/4 : 7 = 5,25 : 7 = 0,75
