Understanding how to convert percentages to decimals is a fundamental skill in mathematics and has practical applications in various real-life scenarios, from calculating discounts to understanding financial data. The concept of "percent" literally means "per hundred," so converting a percentage to a decimal involves expressing it as a fraction of 100.

Calculate Decimals from Percents Now! →The Basic Method: Dividing by 100
The most straightforward method to find the decimal of a percent is to divide the percentage by 100. This is because a percentage is essentially a ratio out of 100. For example, if you want to convert 25% to a decimal, you would perform the following calculation:
25% = 25 / 100 = 0.25
Therefore, the decimal equivalent of 25% is 0.25.
The Shortcut: Moving the Decimal Point
A quicker way to convert a percentage to a decimal is to move the decimal point two places to the left and remove the percent sign. This method is based on the same principle as dividing by 100 but offers a faster approach. Consider the example of converting 75% to a decimal:
- Start with 75%.
- Imagine a decimal point after the 5: 75.%.
- Move the decimal point two places to the left: .75
- Add a leading zero if needed: 0.75
Thus, 75% is equal to 0.75 as a decimal.
Examples and Special Cases
- Converting 10%: 10 / 100 = 0.10 or 0.1
- Converting 125%: 125 / 100 = 1.25
- Converting 0.5%: 0.5 / 100 = 0.005
Notice that percentages greater than 100 will have a decimal value greater than 1, and percentages less than 1 will have a decimal value less than 0.01.
