So I have this basic code:

But the fractional alignment looks awful, any tips to fix this?

```
\documentclass[11pt, a4paper]{report}
\usepackage{bm}
\usepackage{amsfonts, graphicx, verbatim, amsmath,amssymb, amsthm, mathrsfs, eufrak}
\usepackage{color}
\usepackage{array}
\usepackage{setspace}% if you must (for double spacing thesis)
\usepackage{fancyhdr}
\usepackage{enumitem}
\usepackage{tikz}
\usepackage{parskip}
\usepackage{lipsum}
\usepackage{floatrow}
\usepackage{commath}
\providecommand{\U}[1]{\protect\rule{.1in}{.1in}}

\begin{document}

Let $h$ be a linear mapping of $V_1$ into $V_2$. Let
\[
h^0 = \frac{1}{\abs G} \sum_{t\in G} (\rho_t^2)^{-1} h \rho_t^1
\]
where $\abs G$ is the order of $G$. Then
\begin{enumerate}[label=(\roman*)]
\item If $\rho^1$ and $\rho^2$ are not isomorphic then we have $h^0=0$
\item If $V_1 = V_2$ and $\rho^1 = \rho^2$, $h^0$ is a scalar multiple of the identity, the scalar being $\frac{1}{n} Tr(h)$ where $n = \dim(V_1)$
\end{enumerate}

\end{document}

```

as you notice, it looks awful.
