Multiply as if they were not decimals, ie ignore the decimal points. When you get the answer count the total number of numbers to the right of the decimal points and place the decimal point in your answer that many places from the right.
eg 1.2 x 2.05
12 x 205 = 2406
There are three numbers to the right of the decimal point (.2 and .05)
so the answer is 2.406
