To find the percentage of 7th graders who prefer comedies, we first need to determine the total number of 7th graders surveyed and the number who prefer comedies.
From the table:
- 7th graders who prefer comedies = 19
- Total number of 7th graders = Superhero + Comedy + Drama = 15 + 19 + 15 = 49
Now, we can calculate the percentage of 7th graders who prefer comedies:
\[
\text{Percentage} = \left( \frac{\text{Number of students who prefer comedies}}{\text{Total number of 7th graders}} \right) \times 100
\]
\[
\text{Percentage} = \left( \frac{19}{49} \right) \times 100 \approx 38.7755
\]
Rounding to the nearest whole number, the percentage of 7th graders who prefer comedies is approximately **39%**.
