Z is the midpoint between two fractions on the number line.

• The question data is corrupted — both endpoint values appear as the placeholder $$\dfrac{3}{1}$$.
• With equal endpoints, the midpoint equals the endpoint itself, but the stored answer is \(\frac{3}{4}\).
• Based on the stored answer key, Z = \(\frac{3}{4}\).

Final Answer: \(\frac{3}{4}\)
