#### Answer

$-\frac{1}{11}$, 11

#### Work Step by Step

We are given that a number $a=\frac{1}{11}$. We know that the opposite of a number $a$ is $-a$, so the opposite of $a=\frac{1}{11}$ will be $-a=-\frac{1}{11}$. We know that the reciprocal of a nonzero number $a$ is the number $\frac{1}{a}$, where $a\times\frac{1}{a}=1$ $\frac{1}{a}=11$ $\frac{1}{11}\times11=1$
