Let's analyze the expressions given in the image to determine which are equal to 11.

1. First expression: $\frac{-55}{-5}$
   Simplifying this: $\frac{-55}{-5} = 11$ So, this is equal to 11.

2. Second expression: $-\left(\frac{55}{5}\right)$
   Simplifying the inner part first: $\frac{55}{5} = 11$ Now apply the negative sign: $-11$ This expression is not equal to 11.

3. Third expression: $-\left(\frac{-55}{-5}\right)$
   Simplifying the inner part first: $\frac{-55}{-5} = 11$ Now apply the negative sign: $-11$ This expression is also not equal to 11.

Conclusion:

• The first expression is equal to 11.
• The second and third expressions are not equal to 11.
