Answer 1

To find out how many students participate in after-school clubs, you need to calculate 20% of 100 students.

20% of 100 is calculated as follows:

\[ 20% \times 100 = \frac{20}{100} \times 100 = 20 \]

So, for every 100 students, 20 students are in an after-school club.

The answer is 20.
