# Rational Numbers on the Number Line

We will learn how to represent rational numbers on the number line with the help of the following examples.

1. Represent $$\frac{5}{3}$$ and $$\frac{-5}{3}$$ on the number line.

Solution:

In order to represent $$\frac{5}{3}$$ and $$\frac{-5}{3}$$ on the number line, we first draw a number line and mark a point O on it to represent zero.

Now we find the points X and X' on the number line representing the positive integers 5 and -5 respectively as shown in the below figure.

Now divide the segment OX into three equal parts. Let A and B be the points of division so that OA = AB = BX. By construction, OA is one-third of OX.

Therefore, A represents the rational number $$\frac{5}{3}$$.

Point X' represents -5 on the number line. Now, divide OX' into three equal parts OA', CB' and B'X'. The point A' is such that OA' is one third of OX'. Since X' represents the number -5.

Therefore, A' represents the rational number $$\frac{-5}{3}$$.

2. Represent $$\frac{8}{5}$$ and $$\frac{-8}{5}$$ on the number line.

Solution:

To represent $$\frac{8}{5}$$ and $$\frac{-8}{5}$$ on the number line, on the number line, draw a number line and mark a point O on it to represent zero. Now, mark two points M and M' representing integers 8 and -8 respectively on the number line. Divide the segment OM into five equal parts. Let A, B, C, D be the points of division so that OA = AB = BC = CD = DM. By construction, OA is one-fifth of OM. So, A represents the rational number $$\frac{8}{5}$$.

Now, M' represents -8 on the number line. Divide OM' into five equal parts OA', A'B', B'C', C'D', and D'M'. Since M' represents -8 . Therefore, A' represents the rational number -8/5.
