Explanation:

Step1: Calculate the number of students who voted for Cougar

The formula to find the number of students who voted for a particular mascot is \( \text{Number of students} = \text{Total number of students}\times\text{Percentage of students who voted for that mascot}\).
Given that the total number of students \(n = 400\) and the percentage of students who voted for Cougar \(p=10\%=\frac{10}{100}=\frac{1}{10}\).
So the number of students who voted for Cougar is \(400\times\frac{10}{100}\).
Since \(400\times\frac{10}{100}=\frac{400\times10}{100}=400\div10\) (using the rule \(a\times\frac{b}{c}=\frac{a\times b}{c}\) and \(a\div c=\frac{a}{c}\)).

Answer:

\(400\div10\)
