$\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]$

Answer 2

$\frac{4}{6} + \frac{7}{8} - \frac{5}{8} - \frac{11}{20}$$\frac{4}{6} + \frac{7}{8} = \frac{16+21}{24}[tex] \frac{37}{24} -\frac{37}{24}$ 
 \frac{5}{8} = \frac{37-15}{34} = \frac{22}{24} [/tex]
$\frac{22}{24} - \frac{11}{20} = \frac{110-66}{120} = \frac{44}{120}$
