Answer 1

Answer:

The second number is 20% less than the first number.

Step-by-step explanation:

simplify ratio

$\frac{5}{6} \times \frac{2}{3} \\ = \frac{5}{4}$

Then let first number be 5x, so other will be 4x .

Second number is 5x - 4x = x less than first .

Second number is 5x - 4x = x less than first .Percentage less

$\frac{x}{5x} \times 100 \\ = 20$
