Explanation:

Step1: Convert percentage to decimal

To find \(80\%\) of a number, first convert \(80\%\) to a decimal. \(80\%=\frac{80}{100} = 0.8\)

Step2: Calculate the number of students

Multiply the total number of first - year chemistry students (\(240\)) by the decimal equivalent of the percentage. Let \(n\) be the number of students who have had algebra. Then \(n=0.8\times240\)
