Question

1,25*(-2,3)-1,25-0,7:1,5:0,4*(-5)

Answer 1

Ответ: 41/24 или 1 17/24

Answer 2

Let's break down the expression step by step:

1. First, perform the multiplication and subtraction inside the parentheses: 1.25 * (-2.3) = -2.875

2. Next, perform the addition and subtraction outside the parentheses: -2.875 - 1.25 = -4.125

3. Now, let's tackle the division and multiplication on the right side of the expression: 0.7 ÷ 1.5 = 0.4666666666666667 0.4 * (-5) = -2

4. Finally, perform the division and multiplication on the right side of the expression: 0.4666666666666667 : -2 = -0.23333333333333334

So, the final result of the expression is: -4.125 - (-0.23333333333333334) = -4.125 + 0.23333333333333334 ≈ -3.89167
