Another way of doing fractions in html is by using the <sup> and <sub> tags.

For example <sup>15</sup>&frasl;<sub>16</sub> will result in 1516

If it displays as 15/16 then it usually means there is a conflict in css with the <sup> and <sub> tags.

The sup and sub tags are not supported by all browsers.
