Question

Расставте скобки так чтобы равенство стало верным: 24+12×2=72, 150-60:3=30, 72:36-24×10=60, 150-2×24+12:6=140.

Answer 1

1.(24+12)*2=72; (150-60):3=30; 72:(36-24)*10=60; 150-(2*24+12):6=140

Answer 2

(24+12)×2=72 (150-60):2=90 72:(36-24)×10=60

Answer 3

To make each equation true, we need to correctly place the parentheses to change the order of operations. The order of operations dictates that we should perform operations inside parentheses first, then multiplication and division from left to right, and finally addition and subtraction from left to right. Let's add the parentheses to make each equation true:

1. 24 + (12 × 2) = 24 + 24 = 48 (Not 72)

2. (150 - 60) ÷ 3 = 90 ÷ 3 = 30

3. (72 ÷ 36) - (24 × 10) = 2 - 240 = -238 (Not 60)

4. 150 - (2 × 24) + (12 ÷ 6) = 150 - 48 + 2 = 104 (Not 140)

It appears that there are some mistakes in the original equations, and not all of them can be made true by rearranging parentheses. Please double-check the given equations or clarify any additional rules or constraints that need to be followed for a more accurate solution.
