Answer:

13 classes

Step-by-step explanation:

152 divided by 12 is 12.6666666667 so the remaining number of stundents would not be in a class.

But, we can make a class for that remaining students.

So the answer is 13.

I hope this helped ;)

Answer:

2. 13

Step-by-step explanation:

152 / 12 = 12 2/3

So you have 12 groups with the maximum of 12 students per class. Then there are still (152 - 144) = 8 students left... Obviously these 8 need to be placed in a class also.

The last class does not contain the maximum students (but just 8 I stead of 12), but it is counted as a class just the same.

The least number of classes is 13, which is answer 2.
