Problem:
Multiply
$\left(
\begin{array}{ccc}
 \frac{14}{9} & \frac{1}{3} & -\frac{20}{9} \\
 -2 & \frac{2}{3} & -\frac{17}{9} \\
\end{array}
\right)$ and
$\left(
\begin{array}{cccc}
 -\frac{8}{3} & \frac{4}{9} & \frac{7}{3} & \frac{14}{9} \\
 \frac{20}{9} & \frac{8}{9} & \frac{2}{3} & -\frac{17}{9} \\
 -\frac{5}{9} & -\frac{8}{3} & -\frac{17}{9} & \frac{4}{3} \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{cccc}
 -\frac{176}{81} & \frac{560}{81} & \frac{652}{81} & -\frac{95}{81} \\
 \frac{637}{81} & \frac{128}{27} & -\frac{53}{81} & -\frac{62}{9} \\
\end{array}
\right)$
