When multiplying decimals how do you determine where yo place the decimal in the answer?

1.Multiply the numbers just as if they were whole numbers. 
    *Line up the numbers on the right - do not align the decimal points.

    *Starting on the right, multiply each digit in the top number by each digit in the bottom number, just as with whole numbers.

    *Add the products.

    *Place the decimal point in the answer by starting at the right and moving a number of places equal to the sum of the decimal places in both numbers multiplied.

I hope this Helped!
