Question

mirror lake elementary school has 168 students and chaperones going on the fifth grade class trip. Each bus can hold 54 people. What is the least number of buses needed for the trip?

Answer 1

1 bus=54

3 buses=162
4 buses=216
you will need four buses, because after filling 3 buses, you will have 6 people left, so you will need another bus for them :)
