TeXForm without simplification

Question

I'd like to be able to feed an expression into Mathematica, and have Mathematica convert that expression to TeXForm WITHOUT ANY SIMPLIFICATION WHATSOEVER.

As a trivial example, currently, if I enter

6/9 //TeXForm

MM returns

\frac{2}{3}

I'd like to be able to feed it 6/9 and have it return

\frac{6}{9}

Obviously there are solutions that would effectively involve writing my own parser, but I'm specifically looking for relatively short and clean solutions, if there are any.

Answer 1

HoldForm is your friend:

6/9 // HoldForm // TeXForm

\frac{6}{9}
