Hannah hangs a 2 foot by 4 foot painting on a 5 foot by 10 foot wall. What percentage of the wall is taken up by the painting?
Let's be accurate as possible. Think before you answer.
16
First find the area of the painting: 2 feet * 4 feet = 8 square feet.

Then find the area of the wall: 5 feet * 10 feet = 50 square feet.

Then divide the area of the painting by the area of the wall and multiply by 100% to express the answer as a percentage: 8 square feet / 50 square feet * 100% = 16%.

Therefore, the answer is 16
