Question

a survey of 400 students shows that 15% of them bring their lunch every day. how many students bring their lunch every day?
students

Explanation:

Step1: Convert percentage to decimal

To find 15% of 400, first convert 15% to a decimal by dividing by 100: \( 15\% = \frac{15}{100} = 0.15 \)

Step2: Multiply by total number of students

Multiply the decimal by the total number of students (400) to find the number of students who bring lunch: \( 400 \times 0.15 = 60 \)

Answer:

60
