How can I make the output print like the input, with the short denominator written as a factor in front of the long expression?

enter image description here

I was messing with styles earlier today to do something else, and at one point it started printing like that, so I know it can be done, but then it reverted back.

  • $\begingroup$ For your convenience, you could add your original code. In that way you will help community help you. It's easier copying code instead of writing down from scratch. $\endgroup$ – Tom Zinger Apr 25 '16 at 8:18

  • $\begingroup$ @MichaelE2 Only checked this Q out today - your deleted answer looks very useful! It could be added to $POST to automate it. And maybe a condition on the ratio of LeafCounts could be added. $\endgroup$ – Jens Apr 28 '16 at 16:15

Not sure if all you want is formatted output. With Interpretation you get output you can copy.

Clear[fracform]
fracform[e_] /; Denominator[e] =!= 1 := 
  Interpretation[
   DisplayForm@ RowBox[{ToBoxes[1/Denominator[e]], " ", ToBoxes[Numerator[e]]}], 
   e];
fracform[e_] := e;

fracform[a/b]

  • $\begingroup$ All I want is formatted output, so that when I print my Mathematica sheet to pdf and include it in my latex document it looks more readable. $\endgroup$ – SU3 Apr 25 '16 at 16:56
  • $\begingroup$ So it works, then? (One could also replace Interpretation[..] by its first argument.) $\endgroup$ – Michael E2 Apr 25 '16 at 17:09
