Explanation:

Step1: Recall percentage formula

The formula for percentage is $\text{Percentage}=\frac{\text{Number in category}}{\text{Total number}}\times100\%$. The total number of students is $9 + 45+69 + 27=150$.

Step2: Calculate percentage for Animation

For Animation, with 9 students, $\text{Percentage}=\frac{9}{150}\times100\% = 6\%$.

Step3: Calculate percentage for Science fiction

For Science - fiction, with 45 students, $\text{Percentage}=\frac{45}{150}\times100\%=30\%$.

Step4: Calculate percentage for Horror

For Horror, with 69 students, $\text{Percentage}=\frac{69}{150}\times100\% = 46\%$.

Step5: Calculate percentage for Adventure

For Adventure, with 27 students, $\text{Percentage}=\frac{27}{150}\times100\%=18\%$.

Answer:

Type of movie	Percentage
Science fiction	30%
Horror	46%
Adventure	18%
