How should I express fractions like 15/16ths in HTML?

Question

I know there are HTML entities for 1/2, 1/4, and 3/4, but are there others? Like 1/3 or 1/8? Is there a good way to encode arbitrary fractions?

Answer 1

There is also a standard called MathML. But is for XML unfortunately. However if you have more expressions you might consider switching to basic XML.
