60 oranges were either ripe or unripe.
18 more ripe oranges than unripe oranges.
x + 18 = ripe oranges
x = unripe oranges
x + 18 + x = 60

2x = 42
x = 21
21 are unripe oranges
21 + 18 = 39
39 oranges are ripe.
Ratio of the number of ripe oranges to the number of rotten oranges to the number of unripe oranges.
