To find the difference in population between China and India, we subtract the population of India from the population of China:
1.45×10⁹ - 1.4×10⁹ = 0.05×10⁹
So, there are 0.05×10⁹ (or 5×10⁷) more people in China than in India.
The correct answer is: 5×10⁷
To find out how many more people live in China than in India, we need to subtract India's population from China's population.
China's population: 1.45 × 10^9 (1,450,000,000)
India's population: 1.4 × 10^9 (1,400,000,000)
Subtracting India's population from China's population:
1.45 × 10^9 - 1.4 × 10^9 = 0.05 × 10^9 = 5 × 10^8
Therefore, there are 5 × 10^8 more people living in China than in India.
To find out how many more people live in China than in India, we need to subtract India's population from China's population.
China's population: 1.45 × 10^9
India's population: 1,400,000,000
To subtract these numbers, we can convert China's population from scientific notation to standard notation by multiplying 1.45 by 10 raised to the power of 9 (since 10^9 represents 1 billion).
1.45 × 10^9 = 1,450,000,000
Now we can calculate the difference between the two populations:
1,450,000,000 - 1,400,000,000 = 50,000,000
Therefore, there are 50,000,000 more people living in China than in India. In scientific notation, this is represented as 5 × 10^7. So the correct answer is:
5×10^7
