This template builds nicer-looking common fractions. It takes one, two or three parameters: the optional integer (may be signed), the optional numerator and the required denominator; in this order.

{{fraction|1|2|3}}
1 ⅔ (integer, numerator and denominator)
{{fraction|2|3}}
(numerator and denominator)
{{fraction|3}}
(denominator only)

This template differs from {{frac}} in that it tries to use precomposed glyphs and otherwise just inserts a proper fraction slash and possibly a thin space, but does not superscript the numerator and subscript the denominator.

Examples:

½ ¼ ½ ¾ ⅟7 2⁄7 3⁄7 4⁄7 5⁄7 6⁄7 ¼ ½ ¾ ⅟16 3⁄16 5⁄167⁄16 9⁄16 11⁄16 13⁄16 15⁄16 5⁄32 27⁄32

To allow numerical sorting of a column containing fractions, use {{sortfrac}} instead. It is a combination of {{frac}} and {{sort}}.
