Fraction

In common usage a '''fraction''' is any part of a unit. In mathematics:

*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: ** '''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. ** '''Proper fraction''': A vulgar fraction with a value between zero and one ** '''Improper fraction''': A vulgar fraction with a value greater than 1. ** '''Unit fraction''': A vulgar fraction with a numerator of 1. ** '''Egyptian fraction''': The sum of distinct unit fractions. ** '''Decimal fraction''': A vulgar fraction where the denominator is a power of ten. ** '''Dyadic fraction''': A vulgar fraction in which the denominator is a power of two. *A '''Mixed fraction''': A mixed fraction is an integer plus a proper fraction. *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. *A '''continued fraction''' is an expression such as: :<math>x = a_0 + \frac{1}{a_1 + \frac{1}{a_2 + \frac{1}{a_3+\dots}}} </math> :where the a_i are positive integers. *A '''compound fraction''' is a fraction where the numerator or denominator (or both) contain fractions. *'''Partial fractions''' can be used to decompose a rational function.

In religion: *In some Christian denominations, the '''Fraction''' is the ceremonial act of breaking the bread during Communion. ==External links== * Curricula for Teaching about Fractions * Teaching Fractions: New Methods, New Resources * Worksheets: Identifying Fractions * Worksheets: Improper Fractions to Mixed Numbers * Curricula for Teaching about Equivalent Fractions ''이 페이지는 동음이의어 페이지로서, 같은 이름으로 서로 다른 뜻의 낱말이 있을 경우 사용하는 페이지입니다. 만약 어떤 링크가 이 페이지로 와 있다면, 그 링크를 적절하게 고쳐 주십시오.''be:Дробі fr:Fraction ja:分数 sl:Ulomek sv:Fraktal zh:分數
