[tex]-14 \, \frac{1}{9} = - ( \frac{14 \times 9)}{9} + \frac{1}{9} ) = - \frac{127}{9} [/tex]
[tex]-2 \, \frac{9}{10} = -( \frac{20}{10} + \frac{9}{10} ) = - \frac{29}{10} [/tex]
Therefore
[tex]-14 \, \frac{1}{9} (-2 \, \frac{9}{10} ) = (- \frac{127}{9} )(- \frac{29}{10} ) = \frac{127 \times 29}{90} =40.922[/tex]
