A 2-column table with 4 rows titled What after school activity do you participate in question mark. Column 1 has entries sport, club, extra help, none. Column 2 has entries 40 percent, 35 percent, 15 percent, 10 percent.

Question

The table shows the results of a survey about after-school activities.

If 210 students participated in the survey, how many of those students do not participate in any after-school activities?

students

Answer 1

To find out how many students do not participate in any after-school activities, we can use the percentage given for "none." According to the table, 10% of the students fall into the "none" category.

First, we need to calculate the number of students who represent the 10%:

\[ \text{Number of students who do not participate} = 10% \times 210 \]

Calculating that:

\[ \text{Number of students} = 0.10 \times 210 = 21 \]

Therefore, 21 students do not participate in any after-school activities.
