On the field trip students were split into 5 equal groups. at lunch time 10 students needed to go to the bathroom, while the other 45 went to go eat lunch. how many students were in each group?

The number of students in each group is 11

Step-by-step explanation:

Let x represent the number of students that attended the field trip.

On the field trip students were split into 5 equal groups. It means that the number of students in each group is x/5

At lunch time 10 students needed to go to the bathroom, while the other 45 went to go eat lunch. It means that the total number of students that attended the field trip was

45 + 10 = 55 students

Therefore, x = 55

The number of students in each group would be

55/5 = 11
