Problem:
Multiply the scalar $\frac{5}{7}$ and the matrix
$\left(
\begin{array}{cccc}
 -6 & -8 & 7 & -5 \\
 10 & 7 & 0 & 1 \\
 2 & 10 & 0 & -7 \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{cccc}
 -\frac{30}{7} & -\frac{40}{7} & 5 & -\frac{25}{7} \\
 \frac{50}{7} & 5 & 0 & \frac{5}{7} \\
 \frac{10}{7} & \frac{50}{7} & 0 & -5 \\
\end{array}
\right)$
