Division 

Problem 1:

A group of 120 students is going on a field trip. If the students are divided equally into 8 buses, how many students will be on each bus?

Solution:

To find how many students are on each bus, divide the total number of students by the number of buses:

120÷8 = 15

So, there will be 15 students on each bus.

Problem 2:

A teacher has 96 pencils. She wants to distribute them equally among 12 students. How many pencils will each student receive?

Solution:

To find how many pencils each student will receive, divide the total number of pencils by the number of students:
