Maksim231197 [3]

Using the percentage concept, it is found that 60% of the students voted to donate a telescope.

<h3>What is a percentage?</h3>

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:

  • The total amount is the number of students, which is of b = 500.
  • 300 voted to donate, hence a = 300.

The <em>percentage </em>is given by:

P = \frac{300}{500} \times 100\% = 60\%

60% of the students voted to donate a telescope.
