Answer 1

Надеюсь понятно.. .....

Answer 2

To calculate the expression, let's first simplify the terms inside the parentheses and then perform the multiplication:

1. (3/8 - 1/6) × (2/9 - 2/5) × 27

Step 1: Simplify the terms inside the parentheses. (3/8 - 1/6) = [(3 × 3) - (1 × 4)] / (8 × 3) = (9 - 4) / 24 = 5/24

(2/9 - 2/5) = [(2 × 5) - (2 × 9)] / (9 × 5) = (10 - 18) / 45 = -8/45

Step 2: Perform the multiplication and then multiply by 27. (5/24) × (-8/45) × 27 = (5 × -8 × 27) / (24 × 45) = -1080 / 1080 = -1

The result of the expression is -1.
