Answer 1

Ответ:

1 1/4

Пошаговое объяснение:

3/16 * 1 3/5 : (7 1/2 * 1/10 - 3/5) - 3 1/2 : 4 2/3 = 3/10 : (3/4 - 3/5) - 3/4 =

3/10 : 3/20 - 3/4 = 2 - 3/4 = 1 1/4

По действиям:

1. 7 1/2 * 1/10 = 15/2 * 1/10 = 15/20 = 3/4

2. 3/4 - 3/5 = (3*5 - 3*4)/20 = 3/20

3. 3/16 * 1 3/5 = 3/16 * 8/5 = 3*8 / 16*5 = 3/10

4. 3/10 : 3/20 = 3/10 * 20/3 = 2

5. 3 1/2 : 4 2/3 = 7/2 * 3/14 = 3/4

6. 2 - 3/4 = 1 4/4 - 3/4 = 1 1/4
