How to Convert a Percent to a Fraction

1

Enter a Percentage

Select the PCT format and type a percentage value such as 75 into the input field.

2

Read the Fraction

The fraction appears automatically in the result rows, already simplified to lowest terms. Percentages above 100% produce improper fractions.

3

Copy the Result

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

4

Convert in Reverse

Switch the input format to FRAC to go the other way — type a fraction and read its percentage.

Quick tip: dividing the percent by 100 first gives the decimal, then simplifying turns it into a fraction — the tool does both in one step.

The Conversion Formula

To convert a percent to a fraction, write the percentage over 100, then simplify by dividing both numbers by their greatest common divisor (GCD).

Formula: fraction = percent / 100, then divide top and bottom by their GCD to simplify.

Worked Example: 75%

1

Write over 100

75% = 75/100.

2

Find the GCD

GCD of 75 and 100 is 25.

3

Simplify

75 / 25 = 3 and 100 / 25 = 4, so 75% = 3/4.

Frequently Asked Questions

How do I convert 75% to a fraction?

Write 75% as 75/100, then divide both numbers by their GCD of 25 to get 3/4. The converter does this automatically.

What happens with percentages over 100%?

Percentages above 100% give improper fractions. For example, 150% = 150/100 = 3/2 after simplifying.

How do I convert a decimal percentage like 12.5%?

Divide by 100 to get 0.125, which equals 1/8. Decimal percentages simplify the same way — write over 100 (or 1000) and reduce.

Does the tool simplify the fraction automatically?

Yes. Every result is reduced to its lowest terms by dividing the numerator and denominator by their greatest common divisor.

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.
