    For many decimal problems it is easier to multiply first and then to place the decimal point. Multiply the factors as if they were whole numbers. Disregard the decimal point until you place it in the product. The rule for deciding how to place the decimal point in the product works for all decimal multiplication: The number of decimal places in the product must equal the total number of decimal places in the factors. Division by decimals is similar to division by whole numbers To divide a decimal by a whole number, divide the dividend, disregarding the decimal point. Then place the decimal point in the quotient directly above the decimal point in the dividend. When you divide a decimal by another decimal, there is one more step to the procedure. Change the divisor to a whole number by mentally multiplying the divisor by a power of 10. Then multiply the dividend by the same power of 10 so the quotient will stay the same. This mental math is accomplished by moving the decimal point one place to the right in the divisor and one place to the right in the dividend. Complete the division.
