Answer
$\frac{5}{6}$
Work Step by Step
We can perform vertical addition using the same techniques as horizontal addition. The LCM of the original denominators, 3 and 6, is 6. Therefore, we can rewrite the original fractions with a denominator of 6.
$\frac{2}{3}+\frac{1}{6}=\frac{2\times2}{3\times2}+\frac{1}{6}=\frac{4}{6}+\frac{1}{6}=\frac{4+1}{6}=\frac{5}{6}$
