A half note is equivalent to four beats in 4/4 time. An eighth note is half a beat in the same time signature.
To find out how many eighth note rests would equal the duration of a half note, you can divide the total beats of the half note by the duration of an eighth note:
- Duration of a half note: 4 beats
- Duration of an eighth note: 0.5 beats
Now, divide the beats: \[ \text{Number of eighth notes} = \frac{4 \text{ beats}}{0.5 \text{ beats/eighth note}} = 8 \text{ eighth notes} \]
Since each eighth note rest counts just like an eighth note in duration, it means you would also need 8 eighth note rests to equal the duration of a half note.
So in this case, the answer is none of the provided options, as the correct answer is eight.
