Question

A random sample from the 6th and 7th grade student population was taken to determine which clubs were the most popular.

Answer 1

Using the percentage concept, it is found that 25% of 6th graders are involved in the yearbook club.

What is a percentage?

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

$P = \frac{a}{b} \times 100\%$

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:

$P = \frac{10}{40} \times 100\% = 25\%$
