$\LARGE\tt{}1 - \dfrac{5}{9} \\ \\ \LARGE\tt{} \dfrac{1}{1} - \dfrac{5}{9} \\ \\ \LARGE\tt{} \dfrac{1 \times 9}{1 \times 9} - \dfrac{5}{9} \\ \\ \LARGE\tt{} \dfrac{9}{9} - \dfrac{5}{9} \\ \\ \LARGE\tt{} \dfrac{9 - 5}{9} \\ \\ {\large\boxed{\boxed{  { \LARGE \tt \red{\dfrac{4}{9}} }}}}$

$\LARGE\tt{}2 + \dfrac{7}{9} \\ \\ \LARGE\tt{} \dfrac{2}{1} + \dfrac{7}{9} \\ \\ \LARGE\tt{} \dfrac{2 \times 9}{1 \times 9} + \dfrac{7}{9} \\ \\ \LARGE\tt{} \dfrac{18}{9} + \dfrac{7}{9} \\ \\\LARGE\tt{} \dfrac{18 + 7}{9} \\ \\ {\large\boxed{\boxed{  { \LARGE \tt \blue{ \dfrac{25}{9}} }}}}$
