please answer both

Mary and Larry are given the same sum of money to invest today for five years. Annual interests rates for both investments are the same, but Mary's interest is compounded every month while Larry's is compounded every six months. Who will have the most money at the end of five years? Flo and Moe are planning to have saved the same amount ten years from now. Both put their investments in an account that will earn the same annual interest over the next ten years, but Moe's interest is compounded quarterly while Flo's is compounded just annually. Who has to invest more today, Flo or Moe
