==============================
Solve:
[tex] \large \implies\sf \LARGE \frac{ \blue{12}}{ \green{15}} = \frac{ \green{n}}{ \blue{5}} \\ [/tex]
[tex] \large \implies \sf \LARGE \green{15n} = \blue{60}[/tex]
[tex] \large \implies\sf \LARGE \frac{ \cancel{15}n}{ \cancel{15}} = \frac{60}{ {15}} \\ [/tex]
[tex] \large \implies\sf \LARGE \therefore \orange{ \: n = 4}[/tex]
