I decided to do my problem and Max’s problem.
With my problem I had to divide 8 brownies with me and 5 of my friends. First, we each get 1 brownie which leaves 2 brownies. Then I have to divide 2 brownies by 6, so 2 divided by 6 equals 1/3. When I give 1/3 of a brownie to everyone then we each have 1 1/3 brownies!
Max now has 360 shells after he got 174 new shells so
Max started with 186 shells!
