Question

A 1/2 gallon of paint covers 1/6 of a wall. How much paint is needed to cover the entire wall?

Could u show me how to do this question?

Answer 1

"A 1/2 gallon of paint covers 1/6 of a wall."
So a gallon of paint covers 2/6 of a wall.

2/6 = 1/3

a gallon ⇒ 1/3 of a wall
3 gallons ⇒ 3/3 of a wall (entire wall)
