{{info|'''This template should ''not'' be used in science or mathematical articles, use {{tl|sfrac}} instead.'''}}
{{Uses TemplateStyles|Template:Fraction/styles.css}}
This template builds an alternative form of [[common fraction]]s. The template takes one, two, or three parameters: the optional integer (may be signed), the optional numerator and the required denominator; in this order. 

Please '''do not''' <code>subst:</code>itute it. This template should also ''not'' be used in certain situations; see [[MOS:FRAC]] and {{slink|MOS:MATH#Fractions}}. For science or mathematical articles, use {{tl|sfrac}} instead. To allow numerical sorting of a column containing fractions, use <code>data-sort-value="X.YYY"</code> where <code>X.YYY</code> is a rounded decimal equivalent.  See [[Help:Sorting]] for more information and options. Inside citation templates, use the cleaner {{tl|citefrac}}.

; <code><nowiki>{{fraction|A|B|C}}</nowiki></code> : {{fraction|A|B|C}} (integer, numerator and denominator)
; <code><nowiki>{{fraction|B|C}}</nowiki></code> : {{fraction|B|C}} (numerator and denominator)
; <code><nowiki>{{fraction|C}}</nowiki></code> : {{fraction|C}} (denominator only)
; <code><nowiki>{{fraction}}</nowiki></code> : {{fraction}} (fraction slash only)

== Examples ==
<!--the fractions are separated by commas that are only visible to screen readers because they do not read out the space separators here-->
; Numbers : {{fraction|2}}{{sronly|,}} {{fraction|3}}{{sronly|,}} {{fraction|2|3}}{{sronly|,}} {{fraction|4}}{{sronly|,}} {{fraction|3|4}}{{sronly|,}} {{fraction|5}}{{sronly|,}} {{fraction|2|5}}{{sronly|,}} {{fraction|3|5}}{{sronly|,}} {{fraction|4|5}}{{sronly|,}} {{fraction|6}}{{sronly|,}} {{fraction|5|6}}{{sronly|,}} {{fraction|7}}{{sronly|,}} {{fraction|2|7}}{{sronly|,}} {{fraction|3|7}}{{sronly|,}} {{fraction|4|7}}{{sronly|,}} {{fraction|5|7}}{{sronly|,}} {{fraction|6|7}}{{sronly|,}} {{fraction|8}}{{sronly|,}} {{fraction|3|8}}{{sronly|,}} {{fraction|5|8}}{{sronly|,}} {{fraction|7|8}}{{sronly|,}} {{fraction|16}}{{sronly|,}} {{fraction|3|16}}{{sronly|,}} {{fraction|5|16}}{{sronly|,}} {{fraction|7|16}}{{sronly|,}} {{fraction|9|16}}{{sronly|,}} {{fraction|11|16}}{{sronly|,}} {{fraction|13|16}}{{sronly|,}} {{fraction|15|16}}
; Units : {{fraction|m|s}}{{sronly|,}} {{fraction|km|h}}{{sronly|,}} {{fraction|kg·m|s<sup>2</sup>}}{{sronly|,}} {{fraction|s}}{{sronly|,}} {{fraction|Mbit|s}}

== Notes ==
* <code><nowiki>{{fraction}}</nowiki></code> or <code>&amp;frasl;</code> may be used to print out the fraction slash glyph " &frasl; ".
* For mixed fractions, in some contexts (like link targets) a "+" is generated between the whole number part and fraction part. If this is not desirable, put the whole number part outside the template, and put a [[non-breaking space]] between when the spacing is desirable. For example: "<nowiki>33&amp;nbsp;{{frac|1|3}}</nowiki>".
