✏️ Examples Showing How to Convert a Decimal to a Percent

Example 1: Change 0.123 to a percent

  1. Move the decimal point two places to the right, so it goes between the 2 and the 3. We get 012.3
  2. Remove the unnecessary zero on the left. We get 12.3
  3. 12.3 is not a whole number, so keep the decimal point.
  4. Add the percent sign.

The answer is 12.3%

Example 2: Change 0.50 to a percent

  1. Move the decimal point two places to the right, so it goes after the last 0. We get 050.
  2. Remove the unnecessary zero on the left. We get 50.
  3. 50 is a whole number, so remove the decimal point. We get 50
  4. Add the percent sign.

The answer is 50%

💡 Good to Know

There is no need to write the decimal point if it is at the end of the number: 50. is written as 50.

Moving the decimal point two places to the right is the same as multiplying the number by 100. For example, 0.123 × 100 = 12.3, so 0.123 = 12.3%.

Multiplying by 100 is the inverse of dividing by 100, which is what you do to change a percent to a decimal. See the lesson on converting a percent to a decimal.
