Step 1. Given Information.

The provided expression is $- \frac{7}{18} - \frac{5}{18}$ .

Step 2. Calculation.

Since, the denominators of the first and second fractions of the expression $- \frac{7}{18} - \frac{5}{18}$ are the same, add the numerators of both fractions to calculate the sum.

$\begin{matrix} - \frac{7}{18} - \frac{5}{18} = \frac{- 7 - 5}{18} [write sum of numerators over denominator] \\ - \frac{7}{18} - \frac{5}{18} = - \frac{12}{18} [add] \end{matrix}$

Step 3. Conclusion.

The sum is $- \frac{12}{18}$ .
