  1. Fraction

    A fraction 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. A common, vulgar, or simple fraction consists of an integer numerator, displayed above a line, and a non-zero integer denominator, displayed below that line. The numerator represents a number of equal parts and the denominator indicates how many of those parts make up a whole. For example, in the fraction 3/4, the numerator, 3, tells us that the fraction represents 3 equal parts, and the denominator, 4, tells us that 4 parts make up a whole. The picture to the right illustrates or 3/4 of a cake. Numerators and denominators are also used in fractions that are not simple, including compound fractions, complex fractions, and mixed numerals. Fractional numbers can also be written without using explicit numerators or denominators, by using decimals, percent signs, or negative exponents. An integer such as the number 7 can be thought of as having an implied denominator of one: 7 equals 7/1.
