⚖️Fraction Comparison Calculator

Compare multiple fractions and see the common denominator steps

How to Use the Fraction Comparison Calculator

The Fraction Comparison Calculator sorts multiple fractions by size after finding their common denominator. Comparing fractions with different denominators requires converting them to a shared denominator first — the least common denominator (LCD) of all the values involved. This tool automates that process, which is useful for studying or double-checking homework.

Enter fractions as "numerator/denominator", separated by commas or new lines, and the tool shows the least common denominator along with all fractions sorted from smallest to largest. The table displays each original fraction, its decimal equivalent, and the equivalent numerator once converted to the LCD, so you can see every step of the common-denominator process at a glance. At least 2 valid fractions are required to compare.

Frequently Asked Questions

What format should I use for fractions?

Enter them as "numerator/denominator", separating multiple fractions with commas or new lines. Example: 1/2, 3/4, 2/3

How is the common denominator calculated?

The tool finds the least common multiple (LCD) of all the denominators you entered, then shows the equivalent numerator for each fraction over that LCD.

Can I compare negative fractions too?

Yes, add a minus sign to the numerator to include negative fractions in the size comparison. Example: -1/2
