- If m and n are finite cardinal numbers, the rational number m/n is the relation which any finite cardinal number x bears to any finite cardinal number y when n X x = m X y.
- Similarly, any rational real number is distinct from the corresponding rational number.
- Thus the rational number one, which we will denote by ' r, is not the cardinal number I; for t r is the relation I/I as defined above, and is thus a relation holding between certain pairs of cardinals.
- In mathematical terminology, 1.62 is an irrational number because its properties don't conform to rational number expectations.
