Question

Kiara baked 30 oatmeal cookies and 48 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 cookie. If she wants each container to have the greatest number of cookies possible, how many plastic containers does she need?

Answer 1

what is the largest number that goes into both 30 and 48 ? That number would be 6.
6 goes into 30 five times
6 goes into 48 eight times

so you can have 6 packs---each containing 5 oatmeal cookies and 8 choc chip cookies
