What solution do you think is more elegant for a simple fraction that should be displayed in just one line?

My examples are

  1. $x_F \equiv \frac{p_z}{p^{\rm MAX}_{z}} = \frac{p_z}{\sqrt{s}/2}$
  2. $x_F \equiv \frac{p_z}{p^{\rm MAX}_{z}} = \frac{p_z}{\sfrac{\sqrt{s}}{2}}$
  3. $x_F \equiv \frac{p_z}{p^{\rm MAX}_{z}} = \frac{p_z}{^\sqrt{s}/_2}$

This generates the following (using the xfrac package).

I don't like 2, but I also think that 3 is not very elegant.

  • How is \sfrac defined? Do you enable this command by loading a package? – Mico Aug 16 '13 at 12:43
  • Sorry @Mico I should have put the package link – leoredi Aug 16 '13 at 15:01

It is nearly always best to use the slashed form for fractions in the text:

Sample output


\( x_F \equiv p_z^{}/p^{\mathrm{MAX}}_z = p_z/(\sqrt{s}/2) = 2p_z/\sqrt s \)

Note that I have added brackets to the second fraction.


There is also nicefrac package which provides \nicefrac{<Nr>}{<Dr>}:


\( x_F \equiv \nicefrac{p_z}{p^{\mathrm{MAX}}_z} = \nicefrac{p_z}{(\nicefrac{\sqrt{s}}{2})} = \nicefrac{2p_z}{\sqrt s} \)

\vspace{.5cm}        %% Andrew's method for comparison purpose.
\( x_F \equiv p_z^{}/p^{\mathrm{MAX}}_z = p_z/(\sqrt{s}/2) = 2p_z/\sqrt s \)

    I think, the slashed form looks better. In particular, it does not require to reduce the font size. – Konstantin May 2 '16 at 8:35
