Kiara baked 12 oatmeal cookies and 16 chocolate chip cookies to package in plastic containers for her friends at school. She wants to divide the cookies into identical containers so that each container has the same number of each kind of-sookie. If she wants each container to have the greatest number of cookies possible, how many containers does she need?

1 answer

the HCF of 12 and 16 is 4

so 4 containers will do it, with
number of oatmeal cookies in each to be 3, and the number of choc. cookies to be 4.

the number of cookies in each container would be 7

BUT, she could also have 2 containers, with
6 oatmeals and 8 choc chips cookies in each.
Then the number of cookies in each would be 14

So I would say 2 containers for the greatest number of cookies in each.
