Common fractions

Every reduced fraction with a denominator from 2 through 16, plus the 32nds and 64ths a rule is graduated in — 127 in all, each with a permanent page: exact decimal, percent, equivalent fractions, the bar model, and what it measures in millimetres.

Any other fraction works too. Pages live at /fractions/3-8/ — numerator, dash, denominator, always in lowest terms; /fractions/6-16/ forwards to its reduced form. Or just type the value:
