Multiplying Decimal Numbers

To multiply decimal numbers, perform multiplication as you would with
whole numbers. Then count the number of digits that follow the decimal
point or points in the factors. This total will be the number of digits that
follow the decimal point in the product.

Examples

12:83 7:91 The product will have four digits following the decimal
point.

3499:782 19:41 The product will have five digits following the
decimal point.
