Solve for: (50)/(20)=(5)/(h)

Expression: $\frac{ 50 }{ 20 }=\frac{ 5 }{ h }$

Determine the defined range

$\begin{array} { l }\frac{ 50 }{ 20 }=\frac{ 5 }{ h },& h≠0\end{array}$

Cancel out the common factor $10$

$\frac{ 5 }{ 2 }=\frac{ 5 }{ h }$

Simplify the equation using cross-multiplication

$5h=10$

Divide both sides of the equation by $5$

$\begin{array} { l }h=2,& h≠0\end{array}$

Check if the solution is in the defined range

$h=2$
