## [Groff] Using variables from register within fractions or equations

What would be the best way to use a regularly incremented variable within
fractions?

I teach ESL and I hope to typeset cloze tests where selected individual
words are replaced by a blank space (a short line or underscore) which has
the question number printed below it. I have done this in LaTeX by using
fractions within the math environment paired with a counter as the
denominator:

\newcommand{\pq}{\hspace{1mm} \stepcounter{qnum}
\begin{math}
_\frac{\hspace{3cm}}{\theqnum}
\end{math}
and the following:

I am honored to be with you today at your commencement...

becomes:
I am h_______ to be with you today at your c________ ...
1                                                      2

Is this possible with groff, using eqn perhaps? Is it possible to use
variables from number registers within equations or fractions?
