A certain country is divided into 5 provinces

A certain country is divided into 5 provinces. Each province consists entirely of Progressives and Traditionalists. If each province contains the same number of Traditionalists and the number of Traditionalists in any given province is 1/15 the total number of Progressives in the entire country, what fraction of the country is Traditionalist?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
