How do you multipy decimals?

Answer 1

Put the number one above another like you are doing a multiplication problem without decimals. Don't try to line the numbers up by the decimals. Multiply like you would normally. When you have your multiplication answer, then you count the number of decimal places in the original and put a decimal point that many in from the end of the answer.

1.2

x .27

--------

84

+240

-------

324 Notice that I've ignored the decimal places so far. The next step is to count them in the original numbers. There's one decimal place in 1.2 and two in .27 so there is a total of three decimal places in the original numbers, so I take my answer and put the decimal point 3 spaces in from the right 324 --> .324 , so .324 would be the answer to this example.
