# [Tex/LaTex] Fractions seem too large in a column vector

fractionsmatrices

The fractions in my column vector look too large:

\documentclass{article}
\usepackage{amsmath}

\begin{document}
$\begin{bmatrix} -4 \\ - \frac{5}{2} \\ \frac{9}{2} \end{bmatrix}$
\end{document}


The denominator "2" from "-5/2" actually creeps slightly over the numerator "9" from "9/2". Is this correct behaviour? It looks bad.

\documentclass{article}
$\setstackgap{L}{1.3\baselineskip} \mathbf{X} = \bracketVectorstack{ -4 \\ - \frac{5}{2} \\ \frac{9}{2}}$
