Answer

30

Step-by-step explanation:

If 12 students = 40% then 24 Students=80% so if half of 12 is 6 then half of 40% is 20% so then I add them 40%+40%+20%=100% then 12+12+6=30. Your welcome

This means 4/10 of the class is 12. Letting the total number of students in a class be x, 4/10x=12 so 4x=120. x=30
