Why Convert Fractions and Decimals to Percentages
Fractions and decimals represent parts of a whole, just like percentages. However, percentages provide a common scale based on one hundred, making comparisons easier.
For example, understanding that one half equals fifty percent is often more intuitive than thinking in fractions.
How to Convert a Fraction to a Percentage
To convert a fraction to a percentage, divide the numerator by the denominator and multiply the result by one hundred.
This method works for all fractions, whether proper or improper.
Fraction to Percentage Formula
Fraction to percentage equals numerator divided by denominator, multiplied by one hundred.
Example
If you have the fraction 3 over 4:
Divide 3 by 4 to get 0.75. Multiply 0.75 by one hundred to get 75 percent.
So, three quarters equals seventy five percent.
How to Convert a Decimal to a Percentage
Converting a decimal to a percentage is even simpler. You multiply the decimal by one hundred.
Decimal to Percentage Formula
Decimal to percentage equals decimal value multiplied by one hundred.
Example
If you have the decimal 0.2:
Multiply 0.2 by one hundred to get 20 percent.
This method applies to all decimal values.
Common Conversion Examples
- One half equals 50 percent
