# Calculate: (1001)/(M)=13

## Expression: $\frac{ 1001 }{ M }=13$

Determine the defined range

$\begin{array} { l }\frac{ 1001 }{ M }=13,& M≠0\end{array}$

Multiply both sides of the equation by $M$

$1001=13M$

Swap the sides of the equation

$13M=1001$

Divide both sides of the equation by $13$

$\begin{array} { l }M=77,& M≠0\end{array}$

Check if the solution is in the defined range

$M=77$
