Fractions and Calculation

Abstract

In spoken English certain simple fractions like 1/2 or 1/4 or 3/4 have special names. We do not say ‘one-fourth’ but one quarter, and 1/2 is pronounced as one half. The French have a special name tiers for 1/3 Fractions of this kind, which serve the purposes of everyday life, may be called natural fractions.
