The problem asks to convert **2 1/4 %** (a mixed number percentage) into a fraction and simplify it.

### Step-by-Step Solution:

1. **Convert the mixed number to an improper fraction**:
   - \( 2 \frac{1}{4} = \frac{9}{4} \).

2. **Express the percentage as a fraction**:
   - Percentages mean "per 100," so \( \frac{9}{4} \% \) is equivalent to:
   \[
   \frac{9}{4} \times \frac{1}{100} = \frac{9}{4 \times 100} = \frac{9}{400}
   \]

3. **Simplify the fraction** (if possible):
   - \( \frac{9}{400} \) is already in its simplest form since 9 and 400 have no common factors.

### Final Answer:
\[
\frac{9}{400}
\]
