1.2=\frac{8x}{100}
Variable x cannot be equal to 0 since division by zero is not defined. Divide 8 by \frac{100}{x} by multiplying 8 by the reciprocal of \frac{100}{x}.
1.2=\frac{2}{25}x
Divide 8x by 100 to get \frac{2}{25}x.
\frac{2}{25}x=1.2
Swap sides so that all variable terms are on the left hand side.
x=1.2\times \frac{25}{2}
Multiply both sides by \frac{25}{2}, the reciprocal of \frac{2}{25}.
x=15
Multiply 1.2 and \frac{25}{2} to get 15.
