Question

In Room 1 there were 28 students, in Room 2 there were

29 students, in Room 3 there were 30 students, and in
Room 4 there were 25 students. What was the average
number of students in the 4 rooms?

Answer 1

Add up the number of students in each room so do 28+29+30+25=112

so the total number of students in the four rooms is 112 next we need to divide the total by the number of rooms which there are 4 rooms so we do 112 divided by 4 = 28 therefore the average number of students
In the four rooms is 28
