A wall is 300 square feet.a gallon of paint covers 110 square feet. What is an appropriate conversion factor to help determine h
saveliy_v [14]

Answer:

(1 gallon)/(100 ft^2)

Step-by-step explanation:

(1 gallon)/(100 ft^2) is a good conversion factor.  We could also use (100 ft^2)/(1 gallon), but I like the first, since the calculation is simpler:

(300ft^2)*/(1 gallon)/(100 ft^2) = 3 gallons  [I like multiplication better than division, and especially here, since 300/100 is 3, if my memory is correct.
