Out of 230 racers who started the marathon, 213 completed the race, 12 gave up, and 5 were disqualified. What percentage did not complete the marathon? Round your answer to the nearest tenth of a percent.

%

To determine the percentage of racers who did not complete the marathon, we need to calculate how many racers either gave up or were disqualified, then divide that number by the total number of racers, and finally multiply by 100 to get the percentage.

### Step-by-Step Calculation:

1. **Total racers who did not complete the race:**
   - Racers who gave up: 12
   - Racers who were disqualified: 5
   \[
   12 + 5 = 17
   \]

2. **Total number of racers:**
   \[
   230
   \]

3. **Percentage of racers who did not complete the marathon:**
   \[
   \frac{17}{230} \times 100 \approx 7.39\%
   \]

4. **Rounding to the nearest tenth:**
   \[
   7.4\%
   \]

### Final Answer:
The percentage of racers who did not complete the marathon is **7.4%**.
