Welcome to TeX.SX! Your question is basically about mathjax usage in websites (such as Math.SE), but fortunately, \frac or \dfrac command (for 'better' fractions) work with mathjax

It is nearly always best to use the slashed form for fractions in the text: \documentclass{article} \begin{document} \( x_F \equiv p_z^{}/p^{\mathrm{MAX}}_z = p_z/(\sqrt{s}/2) = 2p_z/\sqrt s \) …
