About this calculator
The Percent to Fraction Calculator converts percentages into simplified fractions. It is useful for common percentage values, test scores, discounts, proportions, and changing between percent, decimal, and fraction forms.
percent to fraction calculator method
Percent means out of 100, so write the percentage over 100 and simplify. Decimal percentages are first converted so the numerator is a whole number.
- percent = percent / 100
- 75% = 75/100 = 3/4
- 12.5% = 12.5/100 = 125/1000 = 1/8
How to use the percent to fraction calculator
- Enter the percentage number.
- Write it as percent over 100.
- If the percentage has decimals, remove them by scaling numerator and denominator.
- Find the greatest common factor.
- Divide numerator and denominator by the GCF.
- Read the simplified fraction.
Worked examples

Percent as a fraction
Because percent means per hundred, every percentage can start as a fraction over 100.
Common percentage fractions
Many everyday percentages have familiar fraction forms, such as 25% = 1/4, 50% = 1/2, and 75% = 3/4.
Learning and homework note
This calculator is for learning, checking, and general educational use. It shows the method so students can compare each step with their own working, but it should not replace learning the underlying fraction rules.
- Check that every denominator is not zero.
- Negative fractions can be written in more than one equivalent form.
- Rounding may affect decimal or percentage displays.
Frequently asked questions
Does this show the working?
Yes. The fraction calculators are designed to show the main steps, not just the final answer.
Does it simplify answers?
Yes. Fraction answers are reduced to lowest terms where simplification is part of the method.
Can denominators be zero?
No. A denominator of zero is undefined in fraction arithmetic.
Can I use negative fractions?
Yes, but pay attention to signs. The calculator normalises signs so the denominator stays positive.
Why might my teacher write the answer differently?
Equivalent fractions and mixed numbers can represent the same value. Check whether the question asks for improper fraction, mixed number, decimal, or simplest form.
