I have understood everything quite well,but I don't understand what is the logic for taking the convergents,is there any rule for which convergent will be the solution?

There is a theorem that says that. This is not something I just cooked up, I wished I had.

So I have find the convergent by trial and error

No, there is a method to find the convergents.
