Math & Science ⇒ Slanted division symbol

[dmt]

How do I make a large forward slash in a math environment for use when showing for example one fraction divided by fraction? A normal forward slash is too small and disappears between the fractions. I assume there is some symbol for making a larger forward slash that would scale up to the size of what it is next to?

Thanks.

Code: Select all

\documentclass{article}
\begin{document}
\[ \left. \frac12 \middle/ \frac34 \right. \]
\end{document}

phi's suggestion doesn't work without a package that defines \middle. Short of that, try

\documentclass{article}
\begin{document}
\[ \left. \frac12 \right/ \left. \frac34 \right. \]
\end{document}

This may screw up if the right side is bigger than the left, in which case you can put the . and the / in opposite places.

\middle only requires eTeX; most current TeX distributions come with most formats built with an eTeX-based system.

so if your latex dist does not provide the \left \middle \right construction, then your latex dist need a complete update (good idea anyways)
