The Make Fraction command (Style > Type Style) enables you to format fractions automatically. This command becomes active when a fraction is selected or the cursor is placed adjacent to (and on the same line as) the characters that make up the fraction. Examples of fractions that could be formatted are: 11/42, 131/416, and 11/4x.

To convert characters into a fraction, select the characters and choose Style > Type Style > Make Fraction.

The characters in the fraction are converted using Baseline Shift and the formatting specified in the Fraction/Price tab of the Preferences dialog box (QuarkXPress/Edit > Preferences > Application > Fraction/Price).
