China and India are the most populous countries in the world. China's population is approximately 1.45 x 10^9, while India's population is approximately 1,400,000,000. How many more people live in China than in India?

Question

A. 5x10^7
B. 5x10^8
C. 5x10^9
D. 5x10^10

Answer 1

To find the difference in population between China and India, we can subtract India's population from China's population.

1.45 x 10^9 - 1.4 x 10^9 = 0.05 x 10^9

This simplifies to:

0.05 x 10^9 = 5 x 10^8

Therefore, the answer is:

B. 5 x 10^8

There are 500,000,000 (or 500 million) more people living in China than in India.

Answer 2

Are you sure?

Answer 3

Let's recalculate to make sure:

China's population = 1.45 x 10^9
India's population = 1.4 x 10^9

Difference = 1.45 x 10^9 - 1.4 x 10^9
Difference = 0.05 x 10^9

This simplifies to:

0.05 x 10^9 = 5 x 10^8

Therefore, the correct answer is:

B. 5 x 10^8

There are indeed 500,000,000 (or 500 million) more people living in China than in India.
