How many people were at the stadium?

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.
