Question

Tiffany baked 36 oatmeal cookies and 42 chocolate chip cookies to package in plastic containers for her teacher 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

6 plastic containers

Step-by-step explanation:

Tiffany baked 36 oatmeal cookies and 42 chocolate chip cookies

The first step is to find the greatest common divisor of both 36 and 42

= 36/6

= 6

= 42/6

= 7

The greatest common divisor is 6

Hence Tiffany needs 6 plastic containers
