A rectangular poster has an area of 22 square feet. It is 3 2/3
feet wide at its base. What is the height of the poster?
To find the height of the poster, we can divide the area of the poster by its width.
22 square feet / 3 2/3 feet = 22 square feet / (11/3) feet.
To divide by a fraction, we can multiply by its reciprocal.
22 square feet * (3/11 feet) = 22/11 square feet = 2 square feet.
The height of the poster is 2 feet.
