The original function is defined in scm/output-lib.scm, and can be
modified easily:

correctFraction = #(lambda (grob)
  (let ((ev (event-cause grob)))
    (format #f "~a/~a"
            (ly:event-property ev 'numerator)
            (ly:event-property ev 'denominator))))

 {
   \override TupletNumber #'text = \correctFraction
   \times 2/3 { c'4 e' g' }
 }
