0.4x=1
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
x=\frac{1}{0.4}
Divide both sides by 0.4.
x=\frac{10}{4}
Expand \frac{1}{0.4} by multiplying both numerator and the denominator by 10.
x=\frac{5}{2}
Reduce the fraction \frac{10}{4} to lowest terms by extracting and canceling out 2.
