To solve the expression \( 25 - \frac{1}{3}(18 + 9) \), follow these steps:

1. **Simplify inside the parentheses**: 
   \[
   18 + 9 = 27
   \]

2. **Multiply by \(\frac{1}{3}\)**:
   \[
   \frac{1}{3} \times 27 = 9
   \]

3. **Subtract from 25**:
   \[
   25 - 9 = 16
   \]

So, the final answer is \( 16 \).
