To multiply two digit decimal numbers, multiply the numbers as you would without the decimals. To put the decimal in the answer, count the number of decimal places in the two numbers and put the decimal in the answer that many places to the left. For example:
5.12 x 6.35 = 32.5120.
If the numbers were 51.2 x 63.5, the answer would be 3251.20.
