I can explain how multiplying a number by a fraction or a whole number changes its size.

The expression 5 × 2/(3 × 5) can be simplified to 1 × 2/3, which equals 2/3.

Multiplying 2/3 by 7/8, a number less than 1, scales the value of 2/3 down.
- 3
Multiplying 2/3 by 8/7, a number greater than 1, scales the value of 2/3 up.
