100=x\times \frac{44}{3.3}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
100=x\times \frac{440}{33}
Expand \frac{44}{3.3} by multiplying both numerator and the denominator by 10.
100=x\times \frac{40}{3}
Reduce the fraction \frac{440}{33} to lowest terms by extracting and canceling out 11.
x\times \frac{40}{3}=100
Swap sides so that all variable terms are on the left hand side.
x=100\times \frac{3}{40}
Multiply both sides by \frac{3}{40}, the reciprocal of \frac{40}{3}.
x=\frac{100\times 3}{40}
Express 100\times \frac{3}{40} as a single fraction.
x=\frac{300}{40}
Multiply 100 and 3 to get 300.
x=\frac{15}{2}
Reduce the fraction \frac{300}{40} to lowest terms by extracting and canceling out 20.
