Answer:
The world's population is 23 times larger than the United States population.
Step-by-step explanation:
United States population = 3x10^8=300,000,000 or 300 million
The World's population = 7x 10^9= 7,000,000,000 or 7 billion
7 billion divided by 300 million = 23.33333333
7000000000 / 300000000 = 23.333333333
