FAQ
How does a fraction simplifier work?
It finds the greatest common divisor (GCD) of the numerator and denominator, then divides both by the GCD to reduce the fraction to lowest terms.
What is the simplest form of a fraction?
A fraction is in simplest form when the numerator and denominator share no common factors other than 1.
Can this simplify negative fractions?
Yes. The tool keeps the sign in the numerator and makes the denominator positive.
What if the denominator is 0?
A denominator of 0 is invalid. The tool will show an error if you enter 0.
Does this tool store my inputs?
No. Everything runs locally in your browser and nothing is uploaded or saved.
