FAQ
How is it simplified?
The GCD (Greatest Common Divisor) is found and both numerator and denominator are divided by it — e.g. 4/8 simplifies to 1/2.
Do mixed numbers (like 2½) work?
Currently only simple fractions (numerator/denominator) are supported. Convert a mixed number to an improper fraction first (2½ = 5/2).
Do negative fractions work?
Yes — you can enter a negative number in either the numerator or denominator.
