Step-by-step explanation: The product of 15.1 and 0.9 will be smaller than 15.1. This is because 0.9 is smaller than 1 and since 15.1 * 1 is 15.1, we know that anything smaller than 1 will result in the product of it and 15.1 being smaller.
The product of 15.1 and 0.9 will be less than the value of 15.1. This is the case because 0.9 is less than one, which means that the product would be a portion of 15.1 instead of a multiplication of 15.1. In this case, the product is 90% of 15.1.
