x - number we are looking for. 

0.2% * x = 12

0.2% =  2/1000

2/1000 * x = 12, we multiply both sides by 1000
2 *x = 12000, we divide both sides by 2
x = 6000

Answer is: 0.2% of 6000 is 12
0.2/100x=12

Simplify both sides of the equation.

0.002x=12

Divide both sides by 0.002.

0.002x / 0.002 = 12 / 0.002

x=6000
