there is quite complicated to see your code, but one way to do it is by using the package enumitem, then your code should be like this:
%Preamble
\usepackage{enumitem}
...
\begin{enumerate}[itemsep=1cm,parsep=0.5cm]
\item $\frac{1}{2}$
\item $\frac{1}{2}$
\end{enumerate}
it lets you set the spacing between items (itemsep) and between the paragraphs within items (parsep). Then, your result will be
-
2The OP's question uses
enumerate*
and a\dfrac
, so not sure this actually solves the issue. Even with default settings, withenumitem
things work fine for me. FYI, it is always best to post a fully compilable MWE including\documentclass
and the appropriate packages. You can usually use thearticle
class (unless the issue is with some septic class). – Peter Grill Nov 30 '18 at 6:28
\frac
instead of\dfrac
, but without a fully compilable MWE including\documentclass
and the appropriate packages that reproduces the problem it is difficult to help. While solving problems can be fun, setting them up is not. Then, those trying to help can simply cut and paste your MWE and get started on solving the problem. – Peter Grill Nov 30 '18 at 6:26
