Let us consider and . First, let us plot .
- Here, the numerator \(3\) is less than the denominator \(4\).
- Then the positive rational number will be between \(0\) and \(1\).
- Now, let us draw a number line and plot \(1\) and \(-1\).
- Then the number has to lie somewhere between \(0\) and \(1\).
- Now we divide the length between \(0\) and \(1\) into equal parts.
- The Denominator gives us the number of equal parts(\(4\)).
- It is \(4\), so we divide it into \(4\) equal parts.
- The numerator tells us the number of parts starting from zero.
- Here, it is \(3\). So we mark the point \(3\) parts away from the zero as shown in the below figure.
Similarly, can be marked using the same procedure because is the corresponding value of .
- We know that it lies between \(0\) and \(-1\). So, we divide it into four equal parts and mark \(3\) parts away from the zero, as shown in the below figure.
