What Are Percents and Decimals?
Percents
A percent is a way of expressing a number as a fraction of 100. The term "percent" literally means "per hundred." For example, 25% means 25 out of 100 or 25/100.
Decimals
A decimal, on the other hand, is a way of representing fractions in the base 10 system. For example, the fraction 1/2 can be represented as 0.5 in decimal form.
The Relationship Between Percents and Decimals
To convert a percent to a decimal, you can follow a simple process:
- Divide the percent by 100. For example, to convert 25% to a decimal, you would calculate:
( \frac{25}{100} = 0.25 )
Quick Conversion Formula
The formula to convert percent to decimal is: [ \text{Decimal} = \frac{\text{Percent}}{100} ]
