Final answer:
When multiplying a decimal less than one by a whole number, the product is smaller than the whole number. When multiplying two whole numbers, the product is larger than the original numbers.
Step-by-step explanation:
When multiplying a decimal less than one by a whole number, the product is always smaller than the whole number. This is because multiplying by a decimal less than one results in shrinking the original quantity. For example, if you multiply 0.5 (a decimal less than one) by 10 (a whole number), the product would be 5, which is smaller than 10.
When multiplying two whole numbers, the product is always larger than the original whole numbers. For example, if you multiply 4 by 3, the product would be 12, which is larger than both 4 and 3.
