Question

if 1/4 of a gallon of paint covers 1/3 of a fence ,how much paint is needed for the entire fence?

Answer 1

Answer:

3/4 gallon

Step-by-step explanation:

Write and solve an equation of ratios:

1/4 gallon       1/3 fence

---------------- = ----------------------

        x              1 whole fence

Then (1/4)(1) = (1/3)(x).  Multiplying both sides by 3 to isolate (solve for) x, we get:

3/4 gallon = x = the amount of paint needed to cover the entire fence
