Frequently Asked Questions

How do you add or subtract fractions with different denominators?

Find a common denominator by multiplying the two denominators together, convert each fraction to that denominator, then add or subtract the numerators. This calculator does that automatically and shows each step.

How do you multiply and divide fractions?

To multiply fractions, multiply the numerators together and the denominators together. To divide, multiply the first fraction by the reciprocal of the second — flip its numerator and denominator, then multiply.

How do I enter a mixed number?

Fill in the whole number field along with the numerator and denominator — for example 1, 1, and 2 for one and a half. Leave the whole number field at 0 for a plain fraction.

How is a fraction simplified?

A fraction is simplified by dividing the numerator and denominator by their greatest common divisor (GCD) until no common factor remains other than 1.

Can I enter negative fractions?

Yes. Enter a negative value in the whole number or numerator field and the calculator handles negative fractions correctly in every operation.
