Пошаговое объяснение:

1) 13,75 * 2 4/11 = 13 75/100 * 2 4/11 = 13 3/4 * 26/11 = 55/4 * 26/11 = 5/2 * 13/1 = 65/2 = 32 1/2

2) 32 1/2 - 7,75 = 32 1/2 - 7 75/100 = 32 1/2 - 7 3/4 = 32 2/4 - 7 3/4 = 31 6/4 - 7 3/4 = 24 3/4.

Первая скобка

3) 4 5/6 : 1 1/3 = 29/6 : 4/3 = 29/6 * 3/4 = 29/2 * 1/4 = 29/8 = 3 5/8

4) 3 5/8 + 14 3/8 = 17 8/8 = 18

5) 18 - 8 5/5 = 18 - 9 = 9

Вторая скобка

6) 24 3/8 : 9 = 195/8 : 9 = 195/8 * 1/9 = 195/72 = 65/24 = 2 17/24
