Answer 3

To solve the given expressions, let's break them down one by one:

А) |-31|-|-33|

Step 1: Evaluate the inner absolute value: |-33| = 33

Step 2: Evaluate the outer absolute value using the result from Step 1: |-31| = 31

The final result is 31.

б) -2.4 - (1.3)

Simply perform the subtraction: -2.4 - (1.3) = -2.4 - 1.3 = -3.7

в) -3/10 : 3/5

Divide the fractions: (-3/10) ÷ (3/5) = (-3/10) × (5/3) = -15/30 = -1/2

г) 3.6 - 2.1

Perform the subtraction: 3.6 - 2.1 = 1.5

д) -3/8 + 5/6

To add these fractions, we first need to find a common denominator. The common denominator for 8 and 6 is 24.

Rewrite the fractions with the common denominator: (-3/8) + (5/6) = (-3/8) × (3/3) + (5/6) × (4/4) = (-9/24) + (20/24) = (20 - 9)/24 = 11/24

The final result is 11/24.
