FractionIn common usage a fraction is any part of a unit. In mathematics:\n\n*A vulgar fraction is a rational number written as one integer (the numerator) divided by a non-zero integer (the denominator). The line that separates the numerator and the denominator is called the Vinculum. Sub-categories of vulgar fraction include:\n** Irreducible fraction: a vulgar fraction "in lowest terms", where the numerator is an integer, the denominator is a positive integer, and the highest common factor of the numerator and the denominator is 1.\n** Proper fraction: A vulgar fraction with a value between zero and one\n** Improper fraction: A vulgar fraction with a value greater than 1.\n** Unit fraction: A vulgar fraction with a numerator of 1.\n** Egyptian fraction: The sum of distinct unit fractions.\n** Decimal fraction: A vulgar fraction where the denominator is a power of ten.\n** Dyadic fraction: A vulgar fraction in which the denominator is a power of two.\n*A Mixed fraction: A mixed fraction is an integer plus a proper fraction.\n*An irrational fraction is, if all fractions must be capable of being expressed as a vulgar fraction, a contradiction in terms. An irrational number is, by definition, not rational i.e. it cannot be expressed as a vulgar fraction.\n*A continued fraction is an expression such as: \n:\n:where the ai are positive integers.\n*A compound fraction is a fraction where the numerator or denominator (or both) contain fractions.\n*Partial fractions can be used to decompose a rational function. \n \nIn religion:\n*In some Christian denominations, the Fraction is the ceremonial act of breaking the bread during Communion.External links\n\n\nCategory:Number |
