common fractions

Halves and thirds

Common fractions are fractions written with a numerator above a denominator, separated by a line: ½, ¾, ⅔.

The term distinguishes this familiar notation from decimal fractions (0.5, 0.75) and other representations.

In everyday speech, people usually just say "fractions"—the qualifier *common* appears mainly in educational contexts.
