Calculate Percentages Easily! →The Basic Principle
The term "percent" literally means "per hundred." Therefore, converting a percentage to a decimal involves dividing that percentage by 100. Here's the formula:
Decimal = Percentage / 100
Step-by-Step Conversion
- Identify the Percentage: Determine the percentage you want to convert (e.g., 25%).
- Divide by 100: Divide the percentage by 100 (e.g., 25 / 100 = 0.25).
- Remove the Percent Sign: The result is the decimal equivalent (e.g., 0.25).
A Quick Shortcut
A faster way to convert is to move the decimal point two places to the left and remove the percent sign. For example:
- 50% becomes 0.50 (or simply 0.5)
- 75.5% becomes 0.755
- 120% becomes 1.20 (or simply 1.2)
Examples
- Example 1: Convert 15% to a decimal.
15 / 100 = 0.15
- Example 2: Convert 8.5% to a decimal.
8.5 / 100 = 0.085
- Example 3: Convert 175% to a decimal.
175 / 100 = 1.75
Why is This Important?
Converting percentages to decimals is crucial for several reasons:
- Calculations: Decimals are easier to work with in mathematical calculations.
- Comparisons: Decimals allow for easy comparison of different proportions.
- Software Compatibility: Many software applications require decimal inputs for percentage-related functions.

Using Decimals to Find Percentages
Once you've converted a percentage to a decimal, you can easily use it to find a percentage of a number. Simply multiply the number by the decimal equivalent of the percentage.
For example, if you want to find 20% of 150, first convert 20% to a decimal (0.20), then multiply: 0.20 * 150 = 30. So, 20% of 150 is 30.
