Question

A school has 617 students. Each class has between 28 and 32 students. Which is the best estimate of the number of classes in the school?

14 classes
20 classes
30 classes
60 classes

Answer 1

20

Explanation:

617/28= 22 (rounded too)

617/32= 19 ( rounded too)

19-22 is teh amount of classes that can be filled with 28 to 32 students.

20 is correct because it is around the amount of classes that there can be. !4 is too little so the number of students should be smaller.

30 and 60 classes are to big. there would only be about 10 or 20 kids per class
