Question

Four 4th grade classes are going on a field trip to the aquarium. Three classes have 18 students and one class has 10. Parents will be driving the students in their own vechicle and each vechicle can hold 5 students.​

Answer 1

13 vehicles (at least) will be needed to transport the students. 18x3= 54+10= 64\5= 12.8. Round 12.8 to the nearest while number is 13

Answer 2

Answer:

They will need 13 buses

If you have 18 in three of the classes you will need three buses per class

Each van holds 5 kids divide 18 by 5 you get 3 (plus a remainder we will get back to that later)

and 2 vans for the class of 10

So far we are at 11 buses

But there is that remainder you will need 2 more for them

So that puts us at 13 buses

Hope this helps
