À propos de Fraction Simplifier

Reducing a fraction means dividing top and bottom by their greatest common divisor — 84/126 becomes the much friendlier 2/3. This simplifier does it for any fraction, including improper ones, and shows the GCD it divided by so you can follow the working. You also get the decimal value and mixed-number form (7/3 → 2 1/3), covering the three ways a fraction is used across homework, cooking measurements and carpentry.

Fonctionnalités clés

What does "lowest terms" mean?
The numerator and denominator share no common factor other than 1 — the fraction cannot be reduced any further, like 2/3.
Can the denominator be negative?
Convention keeps the denominator positive; enter −3/4 rather than 3/−4 and the simplifier normalises the sign automatically.
