There are 37 student that are riding in cars for a field trip. If a car can carry 4 students, how many cars are necessary to take all of the students?

10 cars

Step-by-step explanation:

37 : 4 = 9.25

Because this is dealing with people, not numbers, there can't be a remaining 0.25 person. There's one extra person that doesn't cleanly fit into the 9 other cars, so a tenth car is needed for that person.
