If we let x be how much Troy spent in US dollars, and the ratio between the US dollar and the Swiss franc is 1:2.2, then, it should be proportional to x : 20 1:2.2 :: x:20 Can you do it from here?

By the way, the proportion could also be written \[\frac{1}{2.2} = \frac{x}{20}\]

Relationship between the <something> and the <some other thing> is basically just screaming RATIO! so all you have to do is get what you want the relationship to be about and put them in the form a : b, and reduce it to lowest term as you would a fraction
