Book Free DemoA rational number is one that can be written as the ratio of two integers.
Example:
i) 6 = 12/2.
ii) 9 = 27/3.
iii) 4 = 16/4.
A number line is a way to visualize numbers by placing them along a line that shows their relative sizes.

Order to represent the rational number on the number line:
- We draw a line and mark a point O on it to represent the rational number 0.
- The positive rational numbers will be represented on the number line to the right side of O.
- The negative rational numbers will be represented on the number line to the left side of O.
- If we mark a point A on the line to the right of O to represent 1, then OA = 1 unit.
- Similarly, if we choose a point A' on the line to the left of O to represent -1 then OA' = -1 unit.

Now, we are going to represent the rational number 1/2 on the number line.
For this, we divide the segment OA into equal parts. Let P be the midpoint of segment OA. Then, OP = PA = 1/2 and also we divide the segment OA' into equal parts. In this P' be the midpoint of segment OA', then OP'= P'A = -1/2.
