Answer: 313 in each box.
Step-by-step explanation: So you have 1,565 flying discs, and they are DIVIDED into 5 boxes, you would divide 1,565 by 5, with that, you keep on subtracting down to get to where you cannot subtract anymore, which gets you down to your answer!
NOTE: I was in class at this time, so that's why I didn't type as much as I should! Your welcome!
