Rational numbers are terminating or recurring decimal numbers written in the form of fraction $\frac{a}{b}$ in which 'a' and 'b' are integers and the denominator 'b' not equal to zero. The numbers from -$\infty$ to +$\infty$ are graphically plotted in a single line called number line.

Plotting of Rational Numbers on this number line is the rational numbers on a number line. Rational numbers are both positive and negative. With 0 in the center of the number line the Positive Rational Numbers are plotted in the right of 0 and the Negative Rational Numbers in the left of 0. Between two integers are a infinite Set of rational numbers and between two rational numbers are also a infinite set of other rational numbers.
