Answer:
4
Explanation:
To figure out how many times the population of India is as compared to the US, we take the population of India and divide by the population of the US
Population of India/population of US
1.2*10^9 /300000000
I will change 300000000 into scientific notation by moving the decimal 8 places to the left, so it becomes 3 *10^8
1.2*10^9 /3* 10^8
Now we divide the numerals and subtract the exponents
1.2/ 3 * 10^(9-8)
.4 * 10^1
.4*10
