several friends each had 2/5 of a bag of peanuts left over from game. they realized that they could have bought 2 fewer bags. How many friends went to game.
The smallest positive integer N for which (2/5)*N is also an integer is 5. So if 5 friends went to the game and each had 2/5 bag then they ate 2 bags total. If they had bought 4 bags then they could have bought 2 fewer bags
