Answer
$\frac{3}{11}$
Work Step by Step
Two numbers that are the same distance from 0 but lie on opposite sides of 0 are called opposites of each other.
We know that the opposite of a number $a$ is $-a$, because $a+(-a)=a-a=0$.
Therefore, the opposite of $-\frac{3}{11}$ is $\frac{3}{11}$, because $-\frac{3}{11}+\frac{3}{11}=\frac{3}{11}-\frac{3}{11}=0$.
