Question

Of the 40 randomly chosen students surveyed, 27 are involved in extracurricular activities at school. There are 680 students at the school. Predict the number of students in the school who are involved in after-school activities. (Please answer the right answer and how you got the answer)

Answer 1

It's around 459. So 460 if need to round

Explanation:

So, 40 randomly chosen people do not represent the whole school, but using the ratio 27:40 you are given in the equation, you can divide the number of students (680) by the surveyed students (40) to get 17. What this means is there is 17 groups of 40 in the school, so to distribute the amount of people who are in a after-school activity, you must multiply 17 x 27 to get the assumption of about 459 kids. Hopefully you understand =)
