During his explorations on Earth 2, Bill happened to visit “Numerus Linum”. Bill was excited to visit this place because he had heard a lot of stories about this place. Legend has it that this place is said to have a note of EVERY occupant of the “House of Rational Numbers, Q”. It was also rumored that this place is essentially a huge line which extends forever on both sides and never ends. It is on this line that all these occupants of the house are marked – each occupant has a unique place.

Bill wanted to see if this rumor was actually true, he decided to see the marking for the occupant “12.456”. He knew that this occupant would be between “12” and “13” and so he navigated to the mark 12. What could be his next step to identify “12.456”?
