To find the ratio comparing the number of students who prefer a visual learning style to the total number of student-participants in the survey, we first need to determine the total number of students.
From the table:
- Auditory learning style: 17 students
- Visual learning style: 20 students
- Kinesthetic learning style: 13 students
Total number of students = 17 + 20 + 13 = 50 students.
Now, we set up the ratio of students who prefer visual learning style to the total number of students:
\[ \text{Ratio} = \frac{\text{Number of students who prefer visual learning}}{\text{Total number of students}} = \frac{20}{50} \]
Now we simplify the fraction:
\[ \frac{20}{50} = \frac{2}{5} \]
Thus, the answer is:
