\frac{0.66}{x}=\frac{3.92}{100}
Divide both sides by 100.
\frac{0.66}{x}=\frac{392}{10000}
Expand \frac{3.92}{100} by multiplying both numerator and the denominator by 100.
\frac{0.66}{x}=\frac{49}{1250}
Reduce the fraction \frac{392}{10000} to lowest terms by extracting and canceling out 8.
1250\times 0.66=49x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 1250x, the least common multiple of x,1250.
825=49x
Multiply 1250 and 0.66 to get 825.
49x=825
Swap sides so that all variable terms are on the left hand side.
x=\frac{825}{49}
Divide both sides by 49.
