I don't know if the title explains much what I want to say, but here it is:
$$ \frac{\text{XXXXX }}{\text{YYYYYYYY}} \text{(ZZZZZZZZZZZZ)} $$
I want to move up the ZZZZ sentence so that it is aligned with XXXX.
Thank you for your help

It's not clear what you're asking, but it seems you're abusing math mode:
\documentclass{article}
\begin{document}
\begin{center}
\begin{tabular}[t]{@{}c@{}}
XXXXX \\
\hline
YYYYYYYY
\end{tabular}
(ZZZZZZZZZZZZ)
\end{center}
\end{document}

If you want it in math mode, you can use array
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
\begin{array}{cc}
\text{XXXXX} & \text{(ZZZZZZZZZZZZ)} \\\cline{1-1}
\text{YYYYYYYY}
\end{array}
\]
\end{document}

$$! Use\[...\]instead. See http://tex.stackexchange.com/questions/503/why-is-preferable-to – Jan 18 '15 at 11:27\displaystyledirectives meant to achieve? – Mico Jan 18 '15 at 11:39
