7/9:1 1/6 +2 7/10 : - 1/10-4 1/3* - 4 =?
Помогите решить по действиям!!! ​

Answer 1

7/9 : 1 1/6 + 2 7/10 : (-1/10) - 4 1/3 · (-4) = -9

1) 7/9 : 1 1/6 = 7/9 : 7/6 = 7/9 · 6/7 = 6/9 = 2/3

2) 2 7/10 : (-1/10) = 27/10 ·(-10/1) = -27

3) 4 1/3 · (-4) = 13/3 · (-4) = -52/3 = -17 1/3

4) 2/3 + (-27) = -26 1/3

5) -26 1/3 - (-17 1/3) = -26 1/3 + 17 1/3 = -9

Ответ: (-9).
