The Percentage is a fraction or a ratio in which the value of the whole is always 100

Answer: 21 is equal to 75% of 28.

Let's find 75% of what number will be 21.

Explanation:

Let the required number be a.

Then, 75% of a = 21

(75/100) × a = 21

a = 21 × (100 / 75 )

a = (21 × 100) / 75

a = 28.
