At a football stadium, 5% of the fans in the audience were teenagers. If there were 260 teenagers at the football stadium, what was the total number of people at the stadium?
Find out what number 260 is 5% of.
In the formula a = pb a is the “part” p is the “percent” as a decimal b is the “whole” In this situation, the 260 teenagers is the “part”. 5 is the “percent” (0.05 as a decimal). The total number of people is the “whole”. Substitute into the formula a = pb a = pb 260 = (0.05)b {substituted 260 for a, the “part”, and 0.05 for p, the “percent”} b = 5200 {divided each side by 0.05} There were 5200 people at the stadium.
