    1250/100. 12.5 students is equal to 1% of the total school body. Of the students surveyed 51.667% of them work on the weekends, all you need to do is scale that up to represent a larger population. so ((31/60)*(1250))=total number of students who work on the weekends The same logic can be applied to the other question
