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
This is the answer graphed but it is x>-2
5 x 1/4 = 1 1/4 or 1.25
4 x 1/2 = 2
1.25 + 2 = 3.25 or 3 and 1/4
