A bag contains purple, red and green counters.
For every purple counter there are 9 red counters.
For every 3 red counters there are 5 green ones.
What is the ration of purple counters to green counters?
Give your answer in its simplest form.
P==Purple, R == Red, G ==Green
P / R == 1/9,
R / G == 3 / 5, solve for P, G
P == R / 9
G == 5R / 3
P / G == [R / 9] / [5R / 3] == 1 / 15
