There are 3 students in the Crusty Turtles. They each have 5 erasers. There are 3 students in the Bearded Dragons, and they each have 9 erasers.
Ms. McAdam wants to collect the erasers and divide them evenly to the students at each of those groups. How many erasers did each student get?
Note: e stands for erasers
(3x5)+(3x9)=e
15+27= 4242 ÷ 6= 7
Each student gets 7 erasers.
