Пошаговое объяснение:

1) 9 1/3 : 3 1/2 = 28/3 : 7/2 = 28/3 * 2/7 = 4/3 * 2/1 = 8/3

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

3) 10 - 8 2/7 = 9 7/7 - 8 2/7 = 1 5/7

Это числитель дроби

4) 5 3/28 + 1 1/7 = 5 3/28 + 1 4/28 = 6 7/28 = 6 1/4

5) 6 1/4 : 5 = 25/4 * 1/5 = 5/4 * 1/1 = 5/4 = 1 1/4

6) 1 1/4 - 11/28 = 1 7/28 - 11/28 = 35/28 - 11/28 = 24/28 = 6/7

Это знаменатель дроби

7) 1 5/7 : 6/7 = 12/7 * 7/6 = 2/1 * 1/1 = 2/1 = 2

Это результат дроби

8) 2 : 6/7 = 2 * 7/6 = 14/6 = 7/3 = 2 1/3

9) 1 1/2 : 2 1/4 = 3/2 : 9/4 = 3/2 * 4/9 = 12/18 = 2/3

10) 2 1/3 + 2/3 = 2 3/3 = 3

Это результат всего примера
