How to Compare Fractions

The fastest way to compare two fractions without a calculator is cross-multiplication. If you are comparing a/b and c/d, you multiply a × d and b × c.

The Rule

If a×d is greater than b×c, then the first fraction is larger. If they are equal, the fractions are equivalent.
