Question

You survey 72 randomly chosen students about whether they are going to attend the school play. Twelve say yes. Predict the number of students who attend the school.

Answer 1

1260 students.

Explanation:

If 12 out of 72 said yes, you need to first find the ratio of the students. Do this by dividing 210 by 12.

You get 17.5.

Then multiply the ratio by the amount of students surveyed.

You get 1260, from the problem 17.5 * 72.

Hope this helped :)
