Medals are made of a bronze alloy consisting of three metals copper, tin, and zinc, in the ratio of \(\frac{1}{5} : \frac{1}{18} : \frac{1}{45}\). Given that the mass of one medal is 425 grams, calculate the mass of each of three metals.
The mass of copper = 306 grams
The mass of tin = 85 grams
The mass of zinc = 34 grams
