Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
First find the area of the painting: 2 feet * 4 feet = <<2*4=8>>8 square feet
Then find the area of the wall: 5 feet * 10 feet= <<5*10=50>>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%
