Answer 2

.09

Explanation:

Do it like this:

.2 and move the decimal 1 unit to the right.

Do the same thing with .45

You should end up with 2 x 4.5

2 x 4.5 = 9

And now you can put the decimal points back BUT this time you put it back on the .45 side (only applicable in this situation).

Now you have your answer for .2 x .45 now!
