In a class, the ratio of students who passed to those who failed is 11:2. If 44 students failed, what is the total number of students in the class?
286
Pass:fail ratio is 11:2, so each part equals \(44\div2=22\) (since 44 students failed, corresponding to 2 parts).
Total parts: \(11+2=13\).
Total students: \(13\times22=286\).
Hence, the total number of students in the class is 286.
