To add the fractions $\frac{1}{6} + \frac{2}{18}$, let's follow these steps:

1. Find a common denominator: The least common denominator (LCD) of 6 and 18 is 18.

2. Rewrite fractions with the LCD: $\frac{1}{6} = \frac{3}{18} \quad (\text{since} \ \frac{1}{6} = \frac{1 \times 3}{6 \times 3})$ The second fraction, $\frac{2}{18}$, stays the same.

3. Add the fractions: $\frac{3}{18} + \frac{2}{18} = \frac{5}{18}$

So, $\frac{1}{6} + \frac{2}{18} = \frac{5}{18}$.
