Question

June served 4/9 of fruit punch.how many liters does she have left

Answer 1

Well assuming that the 4/9 means 4/9 L then the answer would be 5/9 because

9/9 - 4/9 = 5/9

Answer 2

Just take 9/9-4/9=5/9, we get 9/9 because that is how much fruit punch that there was when the container was full. Enjoy!=)
