Answer:
Any number greater than 3.
Explanation:
If you multiply 5 by any number greater than 3 and then divide it by 3 it will result in a number bigger than 5.
If you multiply the 5 by a number less than three, and then divide it by 3 it will result in a number less than 5 which makes the equation false.
You also can't multiply 5 by 3 and then divide it by 3 because it will make the answer equal to 5. This makes the equation false.
