Answer: 2.723 gallons

Explanation:

For this question, we have to find an appropriate conversion factor to help determine how many gallons of paint will be needed to paint the wall.


$$Since a gallon of paint covers 110 square feet \\So, $\frac{1 \text { gallon }}{110 \text { sq.feet }}$ will be the conversion factor\\$$\begin{aligned}\therefore & (1)/(100) * 300 \text { gallons } \\&\approx2.723 \text { gallons }\end{aligned}$$
