## Multiplying Decimals

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. × 7. The product will have four digits following the decimal point.

3499. × 19. The product will have five digits following the decimal point.

14 × 3. The product will have two digits following the decimal point. (The second digit behind the decimal point is 0: 49.70 = 49.7.)
