Find the difference between two classes
difference = 36 - 20
difference = 16

Transform the difference to percentage form
percentage = difference/beginning class
percentage = 16/20

Percentage is per hundred, so we should change the denominator to 100, multiply it by 5
percentage = 16/20
percentage = (16 × 5)/(20 × 5)
percentage = 80/100
percentage = 80%

The answer is 80%
