A school has 825 students and 55 teachers. How many students are there per teacher?

Answer 1

Mila Anderson

There are #15# students per teacher in the school.

To find out the number of students per teacher, we must divide the number of students by the number of teachers.

We can do this in steps to make it simple.

#825/55#

Divide both terms by #5#.

#(165cancel825)/(11cancel55)#

Now divide both terms by #11#.

#(15cancel165)/(1cancel11)#

We are left with:

#15/1# which is the same as #15#.

Hence we have #15# students per teacher in the school.

To find the number of students per teacher, divide the total number of students by the total number of teachers:
