Fraction to Percent Calculator

To convert a fraction (or mixed number) to percentage, enter whole number, numerator, and the denominator in the given fields.

This fraction to percent calculator performs necessary arithmetic operations to convert any fraction (proper, improper, or mixed number) to its equivalent percentage notation. 

How to Use the Calculator? 

  • Enter the numerator and denominator of the fraction
  • If it is a mixed number, you can also add the whole number
  • Select the precision of the decimal point
  • Tap ‘Calculate’ & get percentage number

How to Convert Fraction to Percent?

  • Step # 01: Divide Numerator by Denominator to get the decimal notation
  • Step # 02: Multiply the decimal number by 100 to get the percent value

Mathematical Formula:

Percent = p/q * 100

where;

  • p = Numerator
  • q = Denominator

Example:

Suppose we have the fraction as 4/5.

Percent = p/q * 100

Percent = 4/5 * 100

Percent = 0.8 * 100

Percent = 80

Alternative Methods:

There are a couple of other ways by which you can convert fraction to percentage. These include:

Shift Decimal Places 2 Places Right:

  • Divide numerator by denominator to get the decimal number
  • Now instead of multiplying it by 100, simply shift the decimal point 2 places right

Example:

Convert 3/6 to its percent notation.

3/6 = 0.5

Percent = 0.5 (Shift decimal 2 places right) => 50%

More Complicated Method:

  • Simply find a whole number that gives 100 when multiplied by the denominator of the given fraction 
  • Multiply both numerator and the denominator by that number
  • Write the new numerator with a percent sign (%)

Example:

The given fraction is “2/20”

If we multiply 20 by 5, we get 100. So multiply both the numerator and the denominator by 5.

2/20 = 2*5/20*5

= 10/100

= 10% (As 1/100 represents percentage)

Facts about Fractions to Percent Conversion:

  • You can change a fraction to decimal form only by the long division method
  • A  mixed number is always equal to or greater than 1. This is why whenever you convert mixed fractions to percentage, the value will be greater than 100.
