Elizabeth is organizing dessert plates with 15 brownies and 9 chocolate chip cookies. If she wants all the plates to be exactly the same with no brownies or cookies left over, what is the greatest number of dessert plates that Elizabeth can make?
The reason for this is because 15 and 9 are both divisible by 3. 15 divided by 3 is 5 and 9 divided by 3 is 3. 5+3= 8. Therefore, you will need 8 plates.
