Simplify the following text for a Grade 9 native English-speaking person.
Original: ; : ( integer , numerator and denominator ) ; : ( numerator and denominator ) ; : ( denominator only ) This template differs from 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 .
Simplified: where the first argument is the numerator ( or upper number ) , and the second argument is the denominator .
