Answer 3

Let's solve the two mathematical expressions step by step:

1. -2.74 ÷ 3.1 + 24.24 ÷ 2.4

Step 1: Perform the divisions -2.74 ÷ 3.1 ≈ -0.883870968 24.24 ÷ 2.4 = 10.1

Step 2: Add the results of the divisions -0.883870968 + 10.1 ≈ 9.216129032

So, the result of the expression is approximately 9.2161.

2. (1 - 1.3 * 1.6) * (-3.2)

Step 1: Perform the multiplication and subtraction inside the parentheses 1 - 1.3 * 1.6 = 1 - 2.08 ≈ -1.08

Step 2: Multiply the result by -3.2 -1.08 * (-3.2) = 3.456

So, the result of the expression is 3.456.

Therefore, the answers are:

1. ≈ 9.2161
2. 3.456
