Rational Number

Written by Jerry Ratzlaff on . Posted in Algebra

A rational number is any number that can expressed as a ratio (fraction) of two integers numbers  \(\large{ ... , -3, -2, -1, 0, 1, 2, 3, ... }\) .  There is more than one way to write the same ratio of two integers.

  • \(\large{\; 0=\frac{0}{1} }\)
  • \(\large{\; 0.125=\frac{1}{8} }\)
  • \(\large{\; 1.5=\frac{3}{2} }\)
  • \(\large{\; 0.63=\frac{63}{100} }\)
  • \(\large{\; 4\frac{1}{3}=\frac{13}{3} }\)
  • \(\large{\; 7=\frac{7}{1} }\)
  • \(\large{\; -7=\frac{-7}{1} }\)  or  \(\large{\frac{7}{-1} }\)  or  \(\large{ -\frac{7}{1} }\)
  • \(\large{\; 0.\overline{33}=\frac{1}{3}}\)
