To add the fractions \( \frac{2}{6} \) and \( \frac{1}{6} \), you can simply add the numerators since they have the same denominator:
\[ \frac{2 + 1}{6} = \frac{3}{6} \]
You can simplify \( \frac{3}{6} \) by dividing both the numerator and the denominator by their greatest common divisor, which is 3:
\[ \frac{3 \div 3}{6 \div 3} = \frac{1}{2} \]
So, \( \frac{2}{6} + \frac{1}{6} = \frac{1}{2} \).
