Answer :
Final answer:
The ratio of purple counters to green counters is 1:15.
Explanation:
Let's use variables to represent the number of counters. Let's say there are 'p' purple counters, 'r' red counters, and 'g' green counters. We are given 2 ratios: for every purple counter, there are 9 red counters; and for every 3 red counters, there are 5 green counters. We can write the ratios as equations: p:r = 1:9 and r:g = 3:5. To find the ratio of purple to green counters, we can combine the two ratios by multiplying them together, which gives us p:r:g = 1:9:15. Therefore, the ratio of purple counters to green counters is 1:15.Learn more about Ratios here:
