Percentage Increase and Decrease Worksheets

Percent implies “for every hundred” and the sign % is read as percentage and x % is read as x per cent. In other words, a fraction with denominator 100 is called a percent. For example, 20 % means 20/100 (i.e. 20 parts from 100). This can also be written as 0.2.

Basic Formula:

In order to calculate p % of q, use the formula:

(p/100) x q = (pxq)/100

Work out the difference (increase) between the two numbers you are comparing. Then divide the increase by the original number and multiply the answer by 100. % Increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.
