If you are asking a question about the mean value of a multiplicative function, I encourage you to read these two answers:

• Mean Value of a Multiplicative Function close to $n$ in Terms of the Zeta Function
• On the mean value of a multiplicative function: Prove that $\sum\limits_{n\leq x} \frac{n}{\phi(n)} =O(x) $
