We conclude that everyone should receive 2/3 cookie.

Step-by-step explanation:

We know that everyday Mary and Laura walk to Mrs. Peterson's house to visit her. She always gives them each a Swedish cookie. One day when Mary and Laura walked home, they decided they would share their cookies with Baby Carrie.

They have a total of 2 cookies. So 2 cookies should be divided into 3 equal parts.

We calculate 2/3=0.666.

We conclude that everyone should receive 2/3 cookie.
