The expression shown in the image is:

$\frac{1}{2} + \frac{1}{3} + \frac{5}{6}$

Step-by-step solution:

1. Find the Least Common Denominator (LCD): The denominators are 2, 3, and 6. The least common denominator of these numbers is 6.

2. Convert fractions to have the same denominator:

   • $\frac{1}{2} = \frac{3}{6}$
   • $\frac{1}{3} = \frac{2}{6}$
   • $\frac{5}{6}$ remains as $\frac{5}{6}$

3. Add the fractions: $\frac{3}{6} + \frac{2}{6} + \frac{5}{6} = \frac{3 + 2 + 5}{6} = \frac{10}{6}$

4. Simplify the fraction: $\frac{10}{6} = \frac{5}{3}$

Thus, the result is:

$\frac{5}{3} \text{ or } 1 \frac{2}{3}$
