Answer 1

$\frac{213}{364} y$

Answer 2

Если что-то не понятно напиши и я попробую объяснить

Answer 3

To simplify the expression, let's break it down step by step:

1. Multiply the fractions inside the parentheses: (16/3) × (-4/15y) × (-7/23) × (23/7) × (-45/21y)

2. Simplify the fractions: (16/3) × (-4/15y) × (-7/23) × (3/1) × (-45/21y)

3. Simplify the expression inside the parentheses (16/3) × (3/1) = 16: 16 × (-4/15y) × (-7/23) × (-45/21y)

4. Now, let's cancel out some common factors: (16/1) × (1/1) × (-1/1) × (-1/1) × (-15/1) × (-1/1) × (-1/3) × (1/1) × (3/1) × (1/1) × (-5/7y)

5. Finally, multiply the remaining fractions and constants: (-16) × (-15) × (-1/3) × (3) × (-5/7y)

6. Further simplification: 16 × 15 × (1/3) × 5/7y

7. Multiply the constants: 16 × 15 × (5/7y) / 3

8. Calculate the result: (240 × 5) / 21y = 1200 / 21y

The simplified expression is: 1200 / 21y
