Question 1: \((iii) \quad 4\frac{1}{2} \)
Solution:
- This is a positive mixed fraction, consisting of two parts: 4 and 1/2.
- The whole number 4 indicates the starting point, so the fraction lies between 4 and 5.
- Since the denominator is 2, divide the segment between 4 and 5 into 2 equal parts.
- With a numerator of 1, place a dot on the first division from 4, which represents the required fraction on the number line.
