To solve the expression \(-\frac{1}{9} - \frac{3}{4}\), we first need to find a common denominator.

1. The denominators are 9 and 4, and the least common denominator (LCD) of 9 and 4 is 36.
2. Rewrite each fraction with a denominator of 36:

\[
-\frac{1}{9} = -\frac{4}{36}, \quad \frac{3}{4} = \frac{27}{36}
\]

3. Now, subtract the fractions:

\[
-\frac{4}{36} - \frac{27}{36} = -\frac{4 + 27}{36} = -\frac{31}{36}
\]

So, the result is:

\[
-\frac{31}{36}
\]
