The population of a country was estimated to be 1.114 x 10^8. On this day, the population of the world was 3.853 x 10^9.
Lelechka [254]

Step-by-step explanation:

To find how many people lived outside of the country we subtract:

3.853 × 10^{9} - 1.114  × 10^{8}  = 3.7146 ×

To find the percentage of people living inside the country, we divide:\frac{1.114 x10^{8}}{3.853 x10^{9}} =2.8913x10^{-2} percent or 2.89%.  Which is extremely small.
