The given expression is:

\[
\frac{-3 + \sqrt{-27}}{3}
\]

To simplify this, follow these steps:

1. **Simplify the square root of \(-27\)**:
   \[
   \sqrt{-27} = \sqrt{-1 \times 27} = \sqrt{-1} \times \sqrt{27} = i \times \sqrt{27}
   \]
   We know that \(i\) represents the imaginary unit, and \(\sqrt{27} = \sqrt{9 \times 3} = 3\sqrt{3}\).

   So:
   \[
   \sqrt{-27} = 3i\sqrt{3}
   \]

2. **Substitute back into the expression**:
   \[
   \frac{-3 + 3i\sqrt{3}}{3}
   \]

3. **Simplify the fraction**:
   We can now divide both terms in the numerator by 3:
   \[
   \frac{-3}{3} + \frac{3i\sqrt{3}}{3} = -1 + i\sqrt{3}
   \]

Thus, the simplified expression is:
\[
-1 + i\sqrt{3}
\]
