Question

3) Rafael always runs for class president. Last year he got 60 votes. This year he got 42 votes. By what percent was the amount of votes decrease from last year?

Answer 1

Percentage is expressed in terms of 100. In this question, we want to express the amount of decrease in vote in terms of 100(percentage)

The decrease in votes from last year = 60 - 42 = 18

The percentage decrease with respect to the number of votes he got last year is

18/60 * 100 = 30%

The percentage decrease is 30%
