Answer:

The population density of Shanghai is 2.98 times greater than the population density of Beijing

Step-by-step explanation:

we know that

To find the population density, divide the total number of people by the area

step 1

Find the population density of Beijing

$\frac{20,700,000}{16,400}=1,262.2\frac{people}{km^{2}}$

step 2

Find the population density of Shanghai

$\frac{23,700,000}{6,300}=3,761.9\frac{people}{km^{2}}$

step 3

Divide the population density of Shanghai by the population density of Beijing

$3,761.9/1,262.2=2.98$

therefore

The population density of Shanghai is 2.98 times greater than the population density of Beijing
