How to Calculate 20% of 100 (Twenty Percent of One Hundred)

When we talk about percentages, we are referring to parts per hundred. So, 20% means 20 out of every 100 parts. To find 20% of any number, we use a simple multiplication method. Here’s how you can do it:

A percentage is a way to express a number as a fraction of 100. "Percent" means "per hundred," so 20% means 20 out of 100.
Convert Percent to Decimal

To calculate percentages, convert the percent into a decimal. For 20%, you move the decimal point two places to the left. Thus, 20% becomes 0.20.

Take the number you want to find 20% of, in this case, 100, and multiply it by 0.20.

Calculation: 100 x 0.20 = 20

Therefore, 20% of 100 is 20.
Visual Aid

Imagine a big square divided into 100 smaller squares (like a 10 x 10 grid). If you color 20 of these squares, you are showing what 20% of the total grid looks like.

You can follow these steps to find 20% of any number, not just 100.
