Answer:
True
Explanation:
If the product of two numbers is a multiple of 3, it means that the product can be evenly divided by 3 without leaving a remainder.
In order for a number to be evenly divisible by 3, it must be a multiple of 3 itself.
Therefore, if the product of two numbers is a multiple of 3, at least one of the two numbers must be a multiple of 3 as well.
