graph $\frac{1}{2}$ on the number line.

Explanation:

Step1: Analyze the number line

The number line is divided into equal parts. Each part represents (\frac{1}{4}) as (0), (\frac{1}{4}), (\frac{2}{4}), (\frac{3}{4}), (1) are marked.

Step2: Locate (\frac{1}{2})

Since (\frac{1}{2}=\frac{2}{4}), on the number - line, it is the second mark after (0).

Answer:

Mark the point at the second tick - mark after (0) (which is at (\frac{2}{4}) or (\frac{1}{2})) on the given number line.
