A ratio of 1:2 means 1 friend gets 1 part and the other friend gets 2 parts. That's a total of 3 parts.
There is a total of 9000 oranges. Dividing that into 3 parts = 9000/3 = 3000 oranges for each part
First friend gets 1 part, that's 3000 oranges.
Second friend gets 2 parts, that's 6000 oranges.
That's a ratio of 1:2
