The multiplicative inverse (or reciprocal) of a number is the value that, when multiplied by the original number, results in 1.

To find the multiplicative inverse of $-\frac{7}{8}$:

$\text{Multiplicative inverse of } -\frac{7}{8} = -\frac{8}{7}$

Thus, the multiplicative inverse of $-\frac{7}{8}$ is $-\frac{8}{7}$.
