How to Convert a Fraction to a Percent

1

Enter a Fraction

Select the FRAC format and type a fraction such as 3/4 into the input field.

2

Read the Percent

The percentage appears automatically in the result rows. Fractions greater than 1 produce percentages above 100%, e.g. 5/4 = 125%.

3

Click the copy button next to the percent, or use Copy All Results to grab the fraction, decimal, and percent together.

4

Convert in Reverse

Quick tip: the percent is just the decimal value multiplied by 100, so 0.75 and 75% always describe the same amount.

The Conversion Formula

To convert a fraction to a percent, divide the numerator by the denominator to get a decimal, then multiply by 100 and add the percent sign.

Formula: percent = (numerator / denominator) × 100%.

Worked Example: 3/4

1

Divide

3 / 4 = 0.75.

2

Multiply by 100

0.75 × 100 = 75.

3

Add the sign

So 3/4 = 75%.

Frequently Asked Questions

How do I convert 3/4 to a percent?

Divide 3 by 4 to get 0.75, then multiply by 100 to get 75%. The converter does both steps automatically.

Can a fraction give a percentage over 100%?

Yes. Any fraction greater than 1 (an improper fraction) gives more than 100%. For example, 5/4 = 1.25 = 125%.

Why does 1/3 show as 33.33% instead of a round number?

1/3 equals 0.3333... repeating, so as a percentage it is 33.333...% repeating. It is commonly displayed as 33.33% after rounding.

What is the relationship between decimals and percentages?

A percent is simply a decimal multiplied by 100. So 0.5 = 50%, 0.25 = 25%, and 1.0 = 100%. The tool shows both at the same time.

Is this converter free to use?

Yes. The tool runs entirely in your browser, is free to use, and requires no sign-up. Your numbers are never sent to a server.
