Multiply decimals the same way that you multiply whole numbers. Put as many decimal places in your answer (that is, behind the decimal point) as there were in the two numbers that you multiplied (in both of them together).

For example:  12.34 x 5.1;    1234 x 51  =  62934  and, since there were two decimal places in the first number and one decimal place in the second number, there will be three (one + two) decimal places in the answer:

    12.34 x 5.1  =  62.934

Another example:  34.56 x 0.000007  =  0.00024192

because 3456 x 7  =  24192 and, since there were two decimal places in the first number and six decimal places in the second number, there will be two + six= eight decimal places in the answer.
