Understanding Percentages

Percentages are a way of expressing a number as a fraction of 100. The term “percent” literally means “per hundred.” For example, 20 percent means 20 out of 100. This concept is crucial in many areas, including sales, taxes, and discounts.

Calculating 20 Percent of 36

To calculate 20 percent of 36, you can follow these simple steps:

Convert the percentage to a decimal by dividing by 100. For 20 percent, this is ²⁰⁄₁₀₀ = 0.20.
