Solve for V
\left\{\begin{matrix}V=\frac{n}{m}\text{, }&n\neq 0\text{ and }m\neq 0\\V\neq 0\text{, }&m=0\text{ and }n=0\end{matrix}\right.
Solve for m
m=\frac{n}{V}
V\neq 0

mV=n
Variable V cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by V.
\frac{mV}{m}=\frac{n}{m}
Divide both sides by m.
V=\frac{n}{m}
Dividing by m undoes the multiplication by m.
V=\frac{n}{m}\text{, }V\neq 0
Variable V cannot be equal to 0.
