To find the percentage, we need to divide the U.S. population by the world population and then multiply by 100.
Percentage = (U.S. population / world population) x 100
Percentage = (438,000,000 / 9,340,000,000) x 100
Percentage = 4.6855...
Rounding to the nearest tenth of a percent, the answer is 4.7%, which is choice C.
