-8, $-\frac{1}{8}$
We are given that the opposite of a number is 8. We know that the opposite of a number $a$ is the number $-a$. Therefore, $-a=8$, so $a=-8$. Also, we know that the reciprocal of a number is $\frac{1}{a}$, such that $a\times\frac{1}{a}=1$. $\frac{1}{a}=-\frac{1}{8}$ $-8\times-\frac{1}{8}=1$
