How is a fraction simplified?

Divide the numerator and denominator by their greatest common divisor (GCD) to get lowest terms.

What if the fraction is negative?

The sign is typically kept on the numerator in the simplified form.

Yes. The tool uses the Euclidean algorithm for GCD, which works for large integers.
