Painting:
Lisa is painting a fence that is 26 feet long and 7 feet tall. A gallon of paint will cover 350 square feet. Write and solve a proportion to determine how many gallons of paint Lisa will need


(Also can you explain how you solved it? Just in case I've been doing all the other ones wrong)

Answer:

Step-by-step explanation:

First we need to find the area of the fence, since paint covers square feet and squared units refers to area.  The area of the fence is 26 x 7, which is 182 sq ft.  If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom. 1/350 = x/182  Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.
A gallon of paint with cover 365
