To determine the fraction represented by point A on the number line, we first observe that there are 9 tick marks between 0 and 1, which means that each tick mark represents an increment of \( \frac{1}{8} \) because:
\[
\text{Total increments} = 9 - 1 = 8 \quad \Rightarrow \quad \text{Value of each tick mark} = \frac{1}{8}
\]
Now, we count the position of point A. It is labeled on the 4th tick mark.
Starting from 0:
- 1st tick mark = \( \frac{1}{8} \)
- 2nd tick mark = \( \frac{2}{8} = \frac{1}{4} \)
- 3rd tick mark = \( \frac{3}{8} \)
- **4th tick mark = \( \frac{4}{8} = \frac{1}{2} \)**
Thus, point A corresponds to the value \( \frac{1}{2} \).
Therefore, the fraction represented by A on the number line is \( \frac{1}{2} \).
