You'd really just have to divide 112 by 15 to find how many classes the school would need to offer, though you'd probably end up with a remainder, in which you'd have to add another class to accommodate all the students, not just all of them with some left over.
112 ÷ 15 = 7.466666666666667
Lol, as you can see, there is definitely a remainder, but the whole number is 7. So since you'd want to accommodate all the students, you'd probably have to go for 8
The school needs to offer 8 CLASSES to accommodate all the students.
