To find the difference in population between China and 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 need to convert China's population to standard form.
1.45 × 10^9 = 1,450,000,000
Now, we can subtract India's population from China's population to find the difference:
1,450,000,000 - 1,400,000,000 = 50,000,000
Therefore, there are 50,000,000 (50 million) 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 the population of India from the population of China.
China's population is approximately 1.45 × 10^9.
India's population is approximately 1,400,000,000.
To subtract these two numbers, we can convert the population of India from standard notation to scientific notation:
1,400,000,000 = 1.4 × 10^9 (since there are 9 zeros behind 1.4)
Now, we can subtract the two numbers:
1.45 × 10^9 - 1.4 × 10^9 = 0.05 × 10^9
To express this number in scientific notation, we can rewrite it as:
0.05 × 10^9 = 5 × 10^8
Therefore, there are 5 × 10^8 (or 500,000,000) more people living in China than in India.
