Question

A class of 40 students elected a class president. There were 12 votes for Candidate A, and 18 votes for Candidate B. The remaining students in the class did not vote. Which expression gives the percent of voters who voted for Candidate A?

Answer 1

In the class 12 out of a possible 40 people voted for candidate A. There were in total only 30 voters (12 + 18). The percentage that voted for candidate A can be found with the following formula:

$\frac{part}{total} \times 100\%$

Filling in this formula learns us the following:
$\frac{12}{30} \times 100\% = 40\%$

Hence, 40% of the voters voted for candidate A.
