Ok. We have 2 wholes, and 3 people. If there were three, we could hand each one a sandwhich and say '<em>Adios!' </em>if there was 1, we would divide it into thirds. If there was two people with three, each would get one and a half. But, we have three brothers, 2 sandwiches. Each gets a half and a third. Because, three thirds make up a sandwich. You can get each a half. Each gets a half and a third.
