$- \frac{10}{33}$

#### Explanation:

$\frac{20}{33} - \frac{30}{33} = \frac{- 10}{33}$

because

$20 - 30 = - 10.$

$- \frac{10}{33}$

#### Explanation:

Subtract the numerators keeping the same denominator

$\frac{20}{33} - \frac{30}{33} = - \frac{10}{33} = - 0. \dot{3} \dot{0}$

See below.

#### Explanation:

All you really have to do is subtract the numerators if the denominators are the same, which they are. You wouldn't subtract the denominators though.
So, $20$ $-$ $30$ $=$ $- 10$
So your final answer would be $- 10$ over $- 33$.

Hope it helped (:
