\frac{1}{5}x=16
Square both sides of the equation.
\frac{\frac{1}{5}x}{\frac{1}{5}}=\frac{16}{\frac{1}{5}}
Multiply both sides by 5.
x=\frac{16}{\frac{1}{5}}
Dividing by \frac{1}{5} undoes the multiplication by \frac{1}{5}.
x=80
Divide 16 by \frac{1}{5} by multiplying 16 by the reciprocal of \frac{1}{5}.
