Multiplication with Decimals
To multiply numbers involving decimals, multiply them as if they were whole numbers, then place the decimal point in the product so it has as many decimal places as the sum of the decimal places in the factors.
- Count decimal places in each factor.
- Multiply numbers ignoring decimal points initially.
- Place decimal point in product by summing decimal places from factors.
