To determine the percentage of ninth-grade students who belong to more than one club, we'll need to follow these steps:

1. Identify the number of ninth-grade students who belong to exactly two clubs.
2. Identify the number of ninth-grade students who belong to three or more clubs.
3. Calculate the total number of ninth-grade students who belong to more than one club by adding the numbers from steps 1 and 2.
4. Find the total number of students in ninth grade.
5. Calculate the percentage of ninth-grade students who belong to more than one club by dividing the total from step 3 by the total number of ninth-grade students, and then multiplying by 100 to convert the result to a percentage.

Let's go through these steps with the given information:

1. The number of ninth-grade students who belong to exactly two clubs is 33.
2. The number of ninth-grade students who belong to three or more clubs is 12.
3. The total number of ninth-grade students who belong to more than one club is:
[tex]\[ 33 + 12 = 45 \][/tex]
4. The total number of students in ninth grade is 180.
5. To find the percentage of ninth-grade students who belong to more than one club, we perform the following calculation:
[tex]\[ \left( \frac{45}{180} \right) \times 100 = 25.0\% \][/tex]

So, 25.0% of the ninth-grade students belong to more than one club.
