Math & Algebra Tool

Comparing Fractions Calculator

Quickly determine which of two fractions is larger using cross-multiplication or common denominators.

VS

Σ The Formula

a/b vs c/d → (a×d) vs (b×c)

Real World Examples

Standard Fractions
3/5 vs 4/7 → 21 > 20, so 3/5 is larger.
Equivalent Fractions
2/4 vs 1/2 → 4 = 4, so they are equal.

# About This Calculator

Comparing Fractions is a core skill in early algebra. Because the denominator (the divisor) can be different for each fraction, it's not always obvious which value is larger at first glance.

One of the most efficient mathematical ways to compare them is the Cross-Multiplication Method. By multiplying the numerator of the first by the denominator of the second, and vice-versa, you effectively bring both to a common denominator ($b \times d$) and compare only the numerators.

How To Use

  1. Enter the numerator and denominator for the **First Fraction**.
  2. Enter the numerator and denominator for the **Second Fraction**.
  3. Click **Compare Fractions**.
  4. The result will show if the first is greater than, less than, or equal to the second.
