Is the result simplified automatically?

Yes. The output fraction is automatically reduced using the greatest common divisor.

When does division fail?

If the second fraction equals 0, the division would become division by zero and cannot be calculated.

Can I also see decimal and percent values?

Yes. The tool shows the simplified fraction together with decimal and percent results.

What numbers can I enter?

For exact fraction simplification, each numerator and denominator must be a whole number from -10,000,000 to 10,000,000.

FAQ

Why show a mixed number too?

A mixed number can be easier to read than an improper fraction in many everyday cases.

Can I calculate negative fractions?

Yes. Enter a negative numerator to work with negative fractions.

Can I enter decimals or very large numbers?

This calculator simplifies fractions made from whole numbers exactly. Decimal inputs are not supported, and each input is limited to an absolute value of 10,000,000 to prevent precision errors.

When is percent output useful?

It helps when you want to interpret a fraction as a rate, share, or ratio in percent form.
