Problem:
Multiply
$\left(
\begin{array}{ccccc}
 -\frac{1}{3} & \frac{17}{6} & -2 & -\frac{7}{3} & -\frac{3}{2} \\
 -\frac{1}{6} & 2 & \frac{5}{6} & \frac{1}{2} & \frac{5}{2} \\
 -\frac{11}{6} & -\frac{2}{3} & -\frac{7}{3} & 1 & -\frac{5}{3} \\
 \frac{1}{6} & -\frac{3}{2} & \frac{11}{6} & \frac{7}{6} & -\frac{8}{3} \\
 -2 & -\frac{11}{6} & \frac{1}{3} & 3 & \frac{11}{6} \\
\end{array}
\right)$ and
$\left(
\begin{array}{cc}
 \frac{11}{6} & -\frac{8}{3} \\
 \frac{1}{2} & -\frac{7}{3} \\
 0 & \frac{7}{6} \\
 -\frac{11}{6} & \frac{13}{6} \\
 0 & \frac{5}{2} \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{cc}
 \frac{61}{12} & -\frac{607}{36} \\
 -\frac{2}{9} & \frac{49}{12} \\
 -\frac{199}{36} & \frac{31}{18} \\
 -\frac{31}{12} & \frac{19}{18} \\
 -\frac{121}{12} & \frac{253}{12} \\
\end{array}
\right)$
