Answer:
25
Step-by-step explanation:
It takes 1/5 of a gallon of water to fill up a package of water balloon
There are 5 gallons of water in total
Therefore the number of packs of balloons that can be filled can be calculated as follows
= 5 ÷ 1/5
= 5 × 5/1
= 25
Hence 25 packs of the balloon can be filled
