# 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  $$\large{ -\frac{7}{1} }$$
• $$\large{\; 0.\overline{33}=\frac{1}{3}}$$
