Understanding the Basics

Before diving into calculating a percentage of a percentage, let's quickly recap what a percentage represents. A percentage is simply a way of expressing a number as a fraction of 100. So, 25% means 25 out of every 100.

The Formula for Percentage of a Percentage

The easiest way to calculate a percentage of a percentage is to convert both percentages into decimals and then multiply them. Here's the formula:

(Percentage 1 / 100) * (Percentage 2 / 100) * 100 = Percentage of a Percentage

Step-by-Step Calculation

  1. Convert the first percentage to a decimal: Divide the first percentage by 100.
  2. Convert the second percentage to a decimal: Divide the second percentage by 100.
  3. Multiply the decimals: Multiply the two decimal values you obtained in steps 1 and 2.
  4. Convert back to percentage (optional): If you need the answer as a percentage, multiply the result by 100.

Example: Finding 20% of 50%

Let's say you want to find 20% of 50%. Here's how you'd do it:

  1. Convert 20% to a decimal: 20 / 100 = 0.20
  2. Convert 50% to a decimal: 50 / 100 = 0.50
  3. Multiply the decimals: 0.20 * 0.50 = 0.10
  4. Convert back to percentage (optional): 0.10 * 100 = 10%

Therefore, 20% of 50% is 10%.
