Fraction (mathematics) it is hyphenated, or as a number of fractions with a numerator of one, in which case they are not. (For example, "two-fifths" is the fraction and "two fifths" is the same fraction understood as 2 instances of .) Fractions should always be hyphenated when used as adjectives. Alternatively, a fraction may be described by reading it out as the numerator "over" the denominator, with the denominator expressed as a cardinal number. (For example, may also be expressed as "three over one".) The term "over" is used even in the case of solidus fractions, where the numbers are placed left
Algebraic fraction A "complex fraction" is a fraction whose numerator or denominator, or both, contains a fraction. A "simple fraction" contains no fraction either in its numerator or its denominator. A fraction is in "lowest terms" if the only factor common to the numerator and the denominator is 1. An expression which is not in fractional form is an "integral expression". An integral expression can always be written in fractional form by giving it the denominator 1. A "mixed expression" is the algebraic sum of one or more integral expressions and one or more fractional terms. If the expressions "a" and "b"
