A fraction (from Latin fractus, broken) represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.
Normally expressing fractions one says the number divided by the number dividing (dividend by quotient) thus two thirds, three quarters, five sixteenths. In these cases the dividend is more than 1. If The dividend is 1 then one would say a half or one half, a fifth or one fifth.
