This template builds an alternative form of common fractions. 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 subst:itute it. This template should not be used in science or mathematical articles, per and ; use {{sfrac}} instead. To allow numerical sorting of a column containing fractions, use {{sortfrac}} instead. It is a combination of this template and {{sort}}.
{{frac|A|B|C}}- A B⁄C (integer, numerator and denominator)
{{frac|A|B}}- A⁄B (numerator and denominator)
{{frac|A}}- 1⁄A (denominator only)
{{frac}}- ⁄ (fraction slash only)
