Ответ:

3/10

Пошаговое объяснение:

1) 1 2/3 * 1 1/2 = 5/3 * 3/2 = 5/2

2) 5/2 * 2 1/5 = 5/2 * 11/5 = 11/2 = 5 1/2

3) 10 - 5 1/2 = 9 2/2 - 5 1/2 = 4 1/2

4) 1/4 : 9/8 = 1/4 * 8/9 = 1/1 * 2/9 = 2/9

5) 2/9 + 1/3 = 2/9 + 3/9 = 5/9

6) 4 1/2 * 5/9 = 9/2 * 5/9 = 5/2 = 2 1/2

7) 2 1/2 - 1 1/2 = 1

8) 1 : 3 1/3 = 1 : 10/3 = 1 * 3/10 = 3/10
