What is the whole number of a fraction?

The whole numbers are the multiples of 1. The fractions are its parts: its halves, thirds, fourths, fifths, and so on. Since the numerator and denominator are natural numbers, the numerator has a ratio to the denominator. (3 is three tenths of 10.) And the fraction itself has that same ratio to 1. (3/10 is three tenths of 1.) .
