You multiply by 0.2, not 0.02.

When you multiply decimals, just forget the decimals to begin and just multiply the whole numbers together. So, 2x6=12 which is the same as 12 with a decimal after it or 12.. Then, you move the decimal one place to the left (since there is one number behind the decimal point in the problem), and you get 1.2. Does that make sense? (By the way, I'm a math teacher and teach this kind of stuff all the time!)
