Answer 2

It looks like you've provided a mathematical expression:

$3 - \frac{1}{9} \div 2 - \left(\frac{1}{3} - \frac{5}{6}\right).$

Let's solve it step by step:

1. $3 - \frac{1}{9} = \frac{27}{9} - \frac{1}{9} = \frac{26}{9}.$

2. $\frac{26}{9} \div 2 = \frac{26}{9} \times \frac{1}{2} = \frac{26}{18} = \frac{13}{9}.$

3. $\frac{1}{3} - \frac{5}{6} = \frac{2}{6} - \frac{5}{6} = \frac{-3}{6} = -\frac{1}{2}.$

4. Now, $\frac{13}{9} - \left(-\frac{1}{2}\right) = \frac{13}{9} + \frac{1}{2}.$

To add these fractions, find a common denominator, which in this case is $18$:

$\frac{13}{9} + \frac{1}{2} = \frac{13 \times 2}{9 \times 2} + \frac{9 \times 1}{2 \times 9} = \frac{26}{18} + \frac{9}{18} = \frac{35}{18}.$

So, the result of the given expression is $\frac{35}{18}$.
