Answer: 1/45
Step-by-step explanation:
In this kind of question, it is cool to choose a number to represent the total number of flights.
Let's say the total number of flights is 720. If 4/15 of the flights are international, then the total number of international flights are ;
4/15 × 720= 192
Now, we are told the airline flight is divided equally amongst 12 countries. This means each country would have a flight of 192/12, and that equals 16 flights per country.
We now calculate the fraction of each country's flight of the total number of flights.
That would be 16/720 which equals 1/45
