How It Works
This comparing fractions calculator uses established formulas to provide accurate results.
The basic rule:
- Cross multiply: a/b vs c/d → compare a×d with c×b
- Convert to decimals: a/b = a÷b

Frequently Asked Questions
How do you compare fractions with different denominators?
You can either convert both fractions to decimals and compare, or use cross-multiplication: multiply the numerator of the first fraction by the denominator of the second, and vice versa. The larger cross-product tells you which fraction is larger.
What is cross-multiplication for comparing fractions?
For a/b and c/d, compute a×d and c×b. If a×d > c×b, then a/b > c/d. If a×d < c×b, then a/b < c/d. If they are equal, the fractions are equal.
How do you compare fractions with the same denominator?
When fractions have the same denominator, just compare the numerators. The fraction with the larger numerator is the greater fraction. For example, 5/7 > 3/7 because 5 > 3.
