A one half rest (also known as a half note rest) lasts for two beats in 4/4 time.
An eighth note rest lasts for half a beat.
To determine how many eighth note rests are equivalent to a one half rest, you would divide the duration of the half rest by the duration of the eighth rest:
- Duration of one half rest: 2 beats
- Duration of one eighth rest: 0.5 beats
So, you would need:
\[ \text{Number of eighth note rests} = \frac{2 \text{ beats}}{0.5 \text{ beats}} = 4 \text{ eighth note rests} \]
Therefore, 4 eighth note rests are required to represent the same duration as one half rest.
