Solve for \( x \) \[ \frac{3}{x}=9 \] Simplify your answer as much as possible.

To solve for \( x \) in the equation \[ \frac{3}{x} = 9, \] you can start by cross-multiplying. This gives you \[ 3 = 9x. \] Next, to isolate \( x \), divide both sides by 9: \[ x = \frac{3}{9}. \] This simplifies to \[ x = \frac{1}{3}. \] So, the solution is \[ \boxed{\frac{1}{3}}. \]
