Shanghai has 23.723.723, point, 7 million people and an area of 6300\text{ km}^26300 km 2 6300, space, k, m, start superscript, 2, end superscript. How many times as great is the population density of Shanghai as Beijing?

Answer:The population density of Shanghai is 2.98 times greater than the population density of BeijingStep-by-step explanation:we know thatTo find the population density, divide the total number of people by the areastep 1Find the population density of Beijing[tex]\frac{20,700,000}{16,400}=1,262.2\frac{people}{km^{2}}[/tex]step 2Find the population density of Shanghai[tex]\frac{23,700,000}{6,300}=3,761.9\frac{people}{km^{2}}[/tex]step 3Divide the population density of Shanghai by the population density of Beijing[tex]3,761.9/1,262.2=2.98[/tex]thereforeThe population density of Shanghai is 2.98 times greater than the population density of Beijing
