Question

(-2,3-3,91:(-2,3)):(-0,01)·(-0,7)=

Answer 1

3,91:(-2,3)= -1,7
-2,3 - (-1,7)= -0,6
-0,01х(-0,7)=0,007
-0,6:0,007= -85,714286 = -85,71
ОТВЕТ:-85,71

Answer 2

It seems like you have a mathematical expression that needs to be evaluated. However, the expression you provided is not clear and contains some formatting issues. It's not entirely clear what operations you intend to perform.

Let's try to interpret the expression step-by-step:

(-2,3 - 3,91 : (-2,3)) : (-0,01) · (-0,7)

From the expression, it appears that you are using commas (,) instead of periods (.) as decimal separators, and colons (:) for division.

Let's rewrite the expression using the correct symbols:

(-2.3 - 3.91 / (-2.3)) / (-0.01) * (-0.7)

Now, let's solve this step-by-step:

1. First, perform the division inside the parenthesis: (-3.91 / -2.3) ≈ 1.7.

2. Then, perform the subtraction: -2.3 - 1.7 = -4.

3. Next, perform the division: -4 / -0.01 = 400.

4. Finally, perform the multiplication: 400 * (-0.7) = -280.

Therefore, the result of the expression is -280.
