Answer: 2 2/5 gallons
Explanation:
We are provided with the information that Benjamin uses 3/5 gallon of paint to paint 1/4 of the fence.
The number of gallons that he needs to do the entire fence will be gotten by dividing the gallon used by the fraction of fence painted. This will be:
= 3/5 ÷ 1/4
= 3/5 × 4/1
= 12/5
= 2 2/5 gallons
Therefore, 2 2/5 gallons will be needed to do the entire fence.
