What is the relationship between rational numbers and the number line?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Every rational number corresponds to a unique point on the number line, and these points are dense (infinitely many between any two points).
Representation:
- Positive rationals lie to the right of 0
- Negative rationals lie to the left of 0
- Zero is at the center
- Rationals can be plotted by dividing segments appropriately
Example: To plot 2/5:
- Divide the segment from 0 to 1 into 5 equal parts
- Mark the 2nd division point = 2/5
