-4-1/2

To simplify the expression \(-4 - \frac{1}{2}\), follow these steps:

1. Convert \(-4\) to a fraction. \(-4\) can be written as \(-\frac{8}{2}\) (since \(-4\) is the same as \(-\frac{8}{2}\)).

2. Now, add the fractions:

   \[ -\frac{8}{2} - \frac{1}{2} = -\frac{8 + 1}{2} = -\frac{9}{2} \]

So, \(-4 - \frac{1}{2} = -\frac{9}{2}\).
