Question

A 136 students are in the cafeteria. The ratio of students buying lunch to those who brought their lunch is 3:10. How many students brought their lunch?

Answer 1

Given that 136 students are in the cafeteria and the ratio of students buying lunch to those who brought their lunch is 3:10.

This means that for every 3 student buying lunch, there are 10 students who brought their lunch.

The number of students that brought their lunch is obtained as follows:


`(10)/(3+10) *136= (10)/(13) *136= (1,360)/(13) \approx105\ students`
