How to ignore underscores inside mathmode

Question

I want to make the expression inside this a text

\frac{   fa_das_tat_C    }{1+0.2 }

that will not be changed in any way.

Welcome to TeX.SX! Please provide working examples, not just lines of code . \_ should yield underscores, but it does not look nice ;-) — , Jul 23 '15 at 15:17
exactly i've tried _ but it doesnt look too nice so i would prefer another solution. Furthermore do u know any way to online convert latex to swf besides codecogs.com (which doesnt work ;( ) — Revist, Jul 23 '15 at 15:21
Please clarify your intentions: is it by any chance \[ \frac{\textit{some\_identifier}}{n+1} \] (say) what you are looking for? (It doesn’t look good in text style, however.) — GuM, Jul 23 '15 at 15:30
@jknappen Tis might be a duplicate, but not of the one you gave for closing reason. — Gonzalo Medina, Jul 23 '15 at 15:50
You could use \verb$fas_das_tat_C$, especially if it is a name and not a product of many variables. — John Kormylo, Jul 23 '15 at 16:32
Does anyone else think the question title is confusing? All the comments and answers suggest that the OP wants to keep the underscores, not ignore them. — James, Jul 23 '15 at 18:41

I believe that what you want is to transform the numerator into a text style (no italic and no subscript). This should do the trick:

\documentclass{article}

\begin{document}

\begin{equation}
\frac{\mathrm{fa\_das\_tat\_C}}{1+0.2 }
\end{equation}

\end{document}
