\frac{n}{4}=p
Swap sides so that all variable terms are on the left hand side.
\frac{1}{4}n=p
The equation is in standard form.
\frac{\frac{1}{4}n}{\frac{1}{4}}=\frac{p}{\frac{1}{4}}
Multiply both sides by 4.
n=\frac{p}{\frac{1}{4}}
Dividing by \frac{1}{4} undoes the multiplication by \frac{1}{4}.
n=4p
Divide p by \frac{1}{4} by multiplying p by the reciprocal of \frac{1}{4}.
