The numberof players is 15 for each team. So how many teams there are, you times by 15. The number of bats is One Third of the players. So just divide the players by 3 to give you the ammount of bats.
You are adding a number to get the number. There is a pattern. For the number of bats, it's plus 5 or Its multiplying 5 by the number of teams. I hope this helps.
