To add the fractions $\frac{2}{3}$ and $\frac{1}{6}$, follow these steps:

1. Find a common denominator:
   The denominators are 3 and 6. The least common denominator (LCD) is 6.

2. Convert the fractions to have the same denominator:

   • $\frac{2}{3}$ can be converted to a fraction with a denominator of 6 by multiplying both the numerator and the denominator by 2: $\frac{2}{3} = \frac{2 \times 2}{3 \times 2} = \frac{4}{6}$
   • $\frac{1}{6}$ is already with a denominator of 6, so it remains $\frac{1}{6}$.

3. Add the fractions: $\frac{4}{6} + \frac{1}{6} = \frac{4 + 1}{6} = \frac{5}{6}$

So, $\frac{2}{3} + \frac{1}{6} = \frac{5}{6}$.
