Using the percentage concept, it is found that 25% of 6th graders are involved in the yearbook club.
The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
In this problem, 10 out of 10 + 24 + 6 = 40 6th graders are involved in the yearbook club, hence the corresponding percentage is given by:
[tex]P = \frac{10}{40} \times 100\% = 25\%[/tex]
