Answer:3/8 gallons of paint is needed to paint the entire fence.
Step-by-step explanation:
Let x represent the entire area of the fence that is to be painted.
If 1/4 of a gallon of paint is needed to paint 2/3 of a fence, it means that 1/4 of a gallon of paint is needed to paint 2x/3
The number of gallons needed to paint the entire fence would be
(x/4)/(2x/3) = x/4 × 3/2x = 3/8 gallons
