EXPLANATION:
If boys and girls are in the ratio of 5:6 in a class, you can divide them into groups of 5 boys and 6 girls (5+6=11 students per group). Classes like that will have a number of students that is a multiple of 11:
5 boys + 6 girls = 11 students, or
10 boys + 12 girls = 22 students, or
15 boys + 18 girls = 33 students, or
20 boys + 24 girls = 44 students, or
25 boys + 30 girls = 55 students, or ...
