Final answer:
The product would be smaller.
Step-by-step explanation:
In mathematics, the product is the result of multiplying two or more numbers. For example, the product of 3 and 4 is 12 (3 * 4 = 12).
The product would be smaller.
When multiplying decimal numbers, the product becomes smaller when one of the factors is decreased. In this case, 0.3 is smaller than 0.31, so the product would be smaller if the factors were 0.63 and 0.3.
