Question

(8,25*10/11-10)*(11,2/3:2,2/9-6,15)+12,7:)-2,1/2) решите пожалуйста !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

To solve the given expression, let's break it down step by step:

1. Start by simplifying the expression within the innermost parentheses: - (8,25 * 10 / 11 - 10) = 7.5

2. Next, simplify the expression within the next set of parentheses: - (11.2 / 3 : 2.2 / 9 - 6.15) = -6.15

3. Now, substitute the values we obtained from steps 1 and 2 into the remaining expression: - 7.5 * -6.15 + 12.7 = -45.825 + 12.7

4. Finally, perform the addition: - -45.825 + 12.7 = -33.125

Therefore, the solution to the given expression is -33.125.

Please note that the decimal separator used in the expression is a comma (,) instead of a period (.), which is commonly used in English-speaking countries.
