Ratios are very fundamental. Any measurement at all involves ratios.
A natural number is a set of several things, thought of in relation to a single thing.
A fraction is a set of one or more things, thought of in relation to a set of one or more things.
Just like how I defined an integer as an ordered pair of natural numbers, I could define a fraction as an ordered pair of natural numbers. The difference is that these pairs have a different equivalence relation, and different addition / multiplication operations.
Rational numbers
