Answer 7

If you want to prove it, you would select two reduced fractions \(x=a/b\) and \(y=c/d\) such that \(x<y\). Then, look at the numbers \[\frac{ad}{bd}\]\[\frac{bc}{bd}\]We know that \(ad<bc\) and they are integers by our assumption.

If \(bc\neq ad+1\) then \[\frac{ad}{bd}<\frac{ad+1}{bd}<\frac{bc}{bd}\]Otherwise multiply x and y by \(\frac{2}{2}\), and choose \[\frac{2ad+1}{2bd}\]
