Calculate Percents Now →The Basic Principle
The term "percent" literally means "per hundred." Therefore, a percentage represents a ratio out of 100. Converting a decimal to a percent essentially involves expressing that decimal as a fraction with a denominator of 100.
The Two-Step Method: Turning Decimals Into Percents
Here's the most straightforward method:
- Multiply the Decimal by 100: This shifts the decimal point two places to the right.
- Add the Percent Sign (%): This indicates that the number is now expressed as a percentage.
Let's illustrate with examples:
- Example 1: Convert 0.45 to a percent.
- 0.45 * 100 = 45
- Add the percent sign: 45%
- Therefore, 0.45 is equal to 45%.
- Example 2: Convert 1.25 to a percent.
- 1.25 * 100 = 125
- Add the percent sign: 125%
- Therefore, 1.25 is equal to 125%.
- Example 3: Convert 0.03 to a percent.
- 0.03 * 100 = 3
- Add the percent sign: 3%
- Therefore, 0.03 is equal to 3%.
The Shortcut: Moving the Decimal Place
As you become more comfortable with this process, you can use a shortcut. To turning decimals into percents, simply move the decimal point two places to the right and add the percent sign. If you run out of digits, add zeros as placeholders.
- 0.7 = 70% (Move the decimal two places right: 0.7 → 7.0 → 70)
- 2. = 200% (Move the decimal two places right: 2.00 -> 20. -> 200.)
What About Numbers Greater Than 1?
Decimals greater than 1, when converted to percents, will result in values greater than 100%. This simply means that the value is more than the "whole" or the "entire amount". For example:
- 1.5 = 150%
- 2.0 = 200%
