Fraction Simplifier
Reduce any fraction to its lowest terms.
Fractions in lowest terms
Simplifying a fraction means dividing the top and bottom by their greatest common divisor. Eight twelfths reduces to two thirds because both share a factor of four, and this does that instantly for any pair.
It is useful beyond math homework: simplifying a measurement ratio, reducing a recipe scale, or expressing odds in their cleanest form all come down to the same lowest-terms reduction.
Whole and mixed numbers
Improper fractions can be read as mixed numbers once reduced. The calculation runs in your browser and nothing is uploaded. The computation runs on your device and nothing is uploaded.

When should I use this tool?
Use it for math homework, recipe scaling, shop measurements, probability notes, and ratio cleanup.
What is the main limitation?
Zero denominators are invalid and mixed numbers should be entered as improper fractions first.
