Answer:

The hand moved $\bf \frac{3}{4}$ of a complete turn.

Step-by-step explanation:

The hand moved from 3 to 12, that is, it moved:

12 - 3 = 9 hours

In a clock, 12 hours represent a complete turn.

∴ Using the unitary method:

12 hours ⇒ 1 turn

1 hour ⇒ $\frac{1}{12}$ turns

9 hours ⇒ $\frac{1}{12}$ × 9 = $\frac{9}{12}$

= $\bf \frac{3}{4}$ turns (simplified)

∴ The hand moved $\bf \frac{3}{4}$ of a complete turn.
