Fractions • We can describe numbers smaller than one by using decimals or fractions. Today, most systems use decimals, but it is still useful to know how to read and say simple fractions in English

We write: We say: ½ a half OR one half ¼ a quarter OR one quarter ¾ three quarters ⅓ a third OR one third ⅔ two thirds ⅕ a fifth OR one fifth ⅗ three fifths ⅛ an eighth OR one eighth ⅝ five eighths 1½ one and a half 5¾ five and three quarters

Although the system of fractions is not used much these days, we commonly use a few simple fractions in everyday speech, for example: • They phoned half an hour ago. • Hurry up! The bus leaves in a quarter of an hour. • The police station is about three quarters of a mile past the traffic lights.

Pro Tip • Note that after "one and a half", the noun is plural: Go straight on for one and a half kilometres. (OR. . . one kilometre and a half) • We had to wait for one and a half hours. (OR. . . an hour and a half)
