The answer is 20.9984. In order to solve a multiplication problem with decimals, first multiply as if they were not with decimals. Once you have finished adding the 3 rows of numbers (multiplying without decimal places), then the count of the numbers behind the decimal point. In this problem there are 4 numbers behind the decimal point. (Count how many are behind both of them), Beginning in the first number written on the right count 4 spaces between the numbers. When you reach the 4th place of the decimal there.
