An equation asks the viewer to identify what quantity a half rest must be multiplied by to result in a whole rest.

Answer 1

The equation would be:

$\frac{1}{2}x = 1$

Where $x$ represents the quantity that the half rest needs to be multiplied by to obtain a whole rest.

To solve the equation, we can multiply both sides by $2$ to eliminate the fraction:

$2 \cdot \frac{1}{2}x = 2 \cdot 1$

$x = 2$

Therefore, a half rest must be multiplied by $2$ to result in a whole rest.
