Fraction Calculator

Enter two fractions and an operator, get the reduced fraction and its decimal value instantly, right in your browser.

How Fraction Calculator works

Fractions appear everywhere: recipes, engineering ratios, homework, financial splits. This calculator removes the pencil-and-paper steps of finding common denominators and simplifying. Enter two fractions, pick an operator, and the reduced fraction plus its decimal equivalent appear immediately.

Results are auto-reduced to lowest terms, and invalid inputs such as a zero denominator are caught and flagged with a clear message instead of returning a meaningless answer.

Frequently asked questions

Does this fraction calculator work offline?

Yes. All arithmetic is performed locally in your browser; once loaded you can disconnect and keep using it.

Are my inputs sent to a server?

No data ever leaves your device. There is no backend and no network request tied to your calculations.

What operations are supported?

Addition, subtraction, multiplication and division of two fractions. Results are auto-reduced to lowest terms and a decimal is shown.

What if I enter a zero denominator?

Inputs are validated first. A zero denominator, or dividing by a fraction whose numerator is zero, shows a clear error instead of an invalid result.
