A large pizza costs $12.75; three friends decide to split one. Jack takes a third, and then Jill
takes a third of the remainder, and then Tom takes half of what’s left.
(a) How should they split the total cost so that each pays an amount proportional to what he has
eaten so far?
(b) Can they split the remaining pizza so that everyone ends up having eaten the same total
amount? If so, how?
