A class of 72 students is going on a field trip. There are vans for boys and vans for girls. The boys’ vans can each take 7 students, and the girls’ vans can each take 5 students. One group has 30 students, and the other has 42. Each van will be full. Using what you know about multiples, find which group is the boys and which is the girls. Then tell how many vans each group will need. Explain how you know.
