**1. The problem statement, all variables and given/known data**

Determine if the statement is true, n is a fixed positive integer.

If n is divisible by 6, then n is divisible by 9.

**2. Relevant equations**

**3. The attempt at a solution**

I know this statement is false because 6 is divisible by 6, however not divisible by 9. I showed a counterexample, is that enough to demonstrate that it is a false statement?
