The expression is not simplified, because both the numerator and the denominator can be divided evenly
Answer:
Denmark has the greatest population density, While the USA has the least density population
Step-by-step explanation:
When Calculating Population Density you use d = p/a
Which would make the USA density population
USA
29.12 = 272,648,000 / 9,364,520
Denmark
124.72 = 5,248,000/42,077
Ghana
77.21 = 18,339,000/237,533
Where D is the density, P is the population, A = the area.
1 kilometer = 1000 meters so 12 kilometers = 12000 meters
10 laps (400 meters/lap) = 4000 meters
12000/4000 = 3
