331 students went on a field trip. 6 buses were filled and 7 students traveled in cars. How many students were in each bus?

Total number of students = 331

total students that travelled in car = 7

total students that travelled in bus = 331 - 7

= 324

total number of buses = 6

Now,

Total number of students in each bus = total students travelling in bus / total bus

= 324 / 6

= 54 students

So, there were 54 students in each bus.

331--7=324 student in 6 budes each bus will have 324/6 = 54 student in each bus.
