Question

David gives 3 cookies to each of his 4 friends. He splits the last cookie into 4 parts and gives each friend another 0.25 cookie. How many cookies does David give away?

Answer 1

David give 4(3.25)=13 cookies

Explanation:

Each David´s friend receives 3+0.25 cookies

since there are 4 David´s friend, then David give 4(3.25)=13 cookies

Answer 2

David gives 4 * 3 = 12 cookies to his 4 friends.

He splits the last cookie into 4 parts and gives each friend another 0.25 cookie, so he gives 4 * 0.25 = 1 cookie in total.

So, David gives away 12 + 1 = 13 cookies in total.
