Question

-3 1/7*(-8)-2,9:0,1+11/21:(-3 2/3)

Answer 1

- 3 1/7 * (-8) - 2,9 : 0,1 + 11/21 : (-3 2/3) = - 4

1) - 3 1/7 * (-8) = - 22/7 * (-8) = 176/7 = 25 1/7
2) 2,9 : 0,1 = 29
3) 11/21 : (-3 2/3) = 11/21 : (-11/3) = 11/21 * (-3/11) = - (1*1)/(7*1) = - 1/7
4) 25 1/7 - 29 = - 3 6/7
5) - 3 6/7 + (-1/7) = - (3 6/7 + 1/7) = - 3 7/7 = - 4 
Ответ: - 4.

Answer 2

Let's break down the expression step by step:

1. First, calculate -3 1/7*(-8): -3 1/7 * (-8) = -3 1/7 * (-8) = 3 1/7 * 8 = 25

2. Next, calculate 2,9:0,1: 2,9 / 0,1 is undefined because you cannot divide by zero.

3. Now, calculate 11/21:(-3 2/3): 11/21 / (-3 2/3) = 11/21 / (-11/3) = (11/21) * (-3/11) = -1/3

So, the result of the expression is -1/3.
