\frac{1}{3}x=100
Square both sides of the equation.
\frac{\frac{1}{3}x}{\frac{1}{3}}=\frac{100}{\frac{1}{3}}
Multiply both sides by 3.
x=\frac{100}{\frac{1}{3}}
Dividing by \frac{1}{3} undoes the multiplication by \frac{1}{3}.
x=300
Divide 100 by \frac{1}{3} by multiplying 100 by the reciprocal of \frac{1}{3}.
