a) 200,000 times greater
b) 20,000 times greater
c) 2,000 times greater
d) 200 times greater

Answer 1

The population of China is 200,000 times greater than Julie's hometown.

Step-by-step explanation:

To find out how many times greater the population of China is than Julie's hometown, we need to divide the population of China by the population of Julie's hometown. The population of China is 1.4 × 10^9 people, and the population of Julie's hometown is 7,000 people.

So, to calculate the ratio, we divide 1.4 × 10^9 by 7,000. This can be rewritten as (1.4 × 10^9) ÷ (7,000).

Dividing 1.4 × 10^9 by 7,000 gives us 2 × 10^5, which is equivalent to 200,000.

Therefore, the population of China is 200,000 times greater than Julie's hometown.
