China and India are the most populous countries in the world. China’s population is approximately 1.45×10^9 , while India’s population is approximately 1,400,000,000. How many more people live in China than in India?
5×10^10
5×10^9
5×10^7
5×10^8
5×10^10
5×10^9
5×10^7
5×10^8
China has approximately 1.45×10^9 people, while India has approximately 1,400,000,000 people. To find out how many more people live in China than in India, we subtract the population of India from the population of China:
1.45×10^9 - 1,400,000,000 = 5×10^7
Therefore, there are 5×10^7 more people living in China than in India.
1.45×10^9 - 1,400,000,000 = 5×10^7
Therefore, there are 5×10^7 more people living in China than in India.
