+You can use the \texttt{nicefrac} package to get fractions with a diagonal slash. This is an ordinary fraction inline (using the \texttt{frac} command): $\frac{3}{4}$, and this is a ``nice'' fraction inline (using the \texttt{nicefrac} command): $\nicefrac{3}{4}$.
+
+The following array shows the difference between ordinary and ``nice'' fractions in display mode:
+
+\[\begin{array}{ccc}
+
+\frac{3}{4} & & \nicefrac{3}{4}
+
+\end{array}\]
