What does that "1 £ a, b £ n" mean?
I think it's 1 =< a,b =< n .
So the question is talking about the subset of Farey sequence (minus the first term of 0/1) .
If we understand how Farey sequence is expanded for successive values of n, then we can apply that understanding and use mathematical induction to prove bc-ad=1 .
