See the entire solution process below:

#### Explanation:

Multiply each side of the inequality by $\textcolor{red}{3}$ to solve for $n$ while keeping the inequality balanced:

$\textcolor{red}{3} \times \frac{1}{3} n \ge \textcolor{red}{3} \times 9$

$\cancel{\textcolor{red}{3}} \times \frac{1}{\textcolor{red}{\cancel{\textcolor{b l a c k}{3}}}} n \ge 27$

$1 n \ge 27$

$n \ge 27$
