students

Explanation:

Step1: Convert percentage to decimal

To find the number of students, we first convert the percentage \(75\%\) to a decimal. \(75\%=\frac{75}{100} = 0.75\)

Step2: Multiply total number of students by the decimal

We know the total number of students is \(4000\). We multiply \(4000\) by \(0.75\), so \(4000\times0.75\)
