#(define-markup-command (fraction-with-no-line layout props arg1 arg2)
  (markup? markup?)
  #:category other
  #:properties ((font-size 0))
  (let* ((m1 (interpret-markup layout props arg1))
         (m2 (interpret-markup layout props arg2))
         (factor (magstep font-size))
         (padding (* factor 0.2))
         (baseline (* factor 0.6))
         (offset (* factor 0.75)))
    (set! m1 (ly:stencil-aligned-to m1 X CENTER))
    (set! m2 (ly:stencil-aligned-to m2 X CENTER))
    (let* ((stack (stack-lines DOWN padding baseline (list m1 m2))))
      (set! stack
            (ly:stencil-aligned-to stack Y CENTER))
      (set! stack
            (ly:stencil-aligned-to stack X LEFT))
      ;; should have EX dimension
      ;; empirical anyway
      (ly:stencil-translate-axis stack offset Y))))

\markup { \fraction-with-no-line 21 5 }



Though, why not use \center-column with adjusted baseline-skip, etc?
