Frequently asked questions

How is the result simplified?
We compute the GCD of numerator and denominator using Euclid's algorithm and divide both.
Does it handle mixed numbers?
Convert mixed numbers to improper fractions first (e.g., 1¾ = 7/4).
What about negatives?
Yes — negative numerators or denominators work. The simplified result keeps the sign on the numerator.
