Let's assume that the smaller of the two positive numbers is x. Then we can express the larger number as 3x, since it is three times the smaller number.
We are given that the product of the two numbers is 108, so we can write:
x * 3x = 108
Simplifying this equation, we get:
3x^2 = 108
Dividing both sides by 3, we get:
x^2 = 36
Taking the square root of both sides, we get:
x = 6
Since x is the smaller of the two numbers, the larger number is 3x, which is:
3x = 3(6) = 18
Therefore, the two positive numbers are 6 and 18. We can check that their product is indeed 108:
6 * 18 = 108
So the solution is that the two positive numbers are 6 and 18.
