Final answer:
When multiplying a whole number by a decimal number, the product can have decimal places.
Step-by-step explanation:
The product could have one decimal place. When multiplying a whole number with a decimal number, the decimal point in the product is determined by the total number of decimal places in the factors.
For example, if we multiply 4 (a whole number) by 3.2 (a decimal number with one decimal place), the product is 12.8 (with one decimal place).
In general, if we multiply a whole number by a decimal number with n decimal places, the product will have n decimal places.
