0.04=x\times 0.002
Multiply 0.01 and 0.2 to get 0.002.
x\times 0.002=0.04
Swap sides so that all variable terms are on the left hand side.
x=\frac{0.04}{0.002}
Divide both sides by 0.002.
x=\frac{40}{2}
Expand \frac{0.04}{0.002} by multiplying both numerator and the denominator by 1000.
x=20
Divide 40 by 2 to get 20.
