Математика: Решите ( 3/4 -8 1/4): 3 1/2 (-1 7/8+3 1/8)х1 3/5 - (-4 2/3 + 5): 10 (-1 3/8+2): 3 1/8

Lagoona030 · Answer

1) 3/4 - 33/4 = - 30/4

- 30/4 : 7/2 = - 60/28 = - 15/7

2) - 15/8 + 25/8 = 10/8

10/8 * 8/5 = 2

3) - 14/3 + 15/3 = 1/3

1/3 * 1/10 = 1/30

4) - 11/8 + 16/8 = 5/8

5/8 * 8/25 = 1/5
