{= \sf \bigg (\dfrac{2}{3}  \times  \dfrac{10}{10}\bigg) - \bigg(\dfrac{4}{5}  \times  \dfrac{6}{6}\bigg)  - \bigg( \dfrac{5}{6}  \times  \dfrac{5  }{5} \bigg)+\bigg( \dfrac{7}{10}  \times 3\bigg) - \bigg( \dfrac{1}{12}  \times 15 \times 15\bigg)}\\\\{ = \sf\dfrac{20}{30}   -\dfrac{24}{30}   -\dfrac{25}{30}  + \dfrac{21}{30}  - \bigg( \dfrac{1}{12}  \times 15  \times 15\bigg)}\\\\{= \sf\dfrac{20 - 24 - 25 - 21}{30}     - \bigg( 18\bigg)}    \\\\{= \sf\dfrac{ - 8}{30}     - 18}\\\\{= \sf\dfrac{ - 8 -562 }{30}}     \\\\    {= \sf\dfrac{ - 570 }{30}}\\\\\sf = 19\\\\\\

 \boxed{{ \sf \bigg (\dfrac{2}{3}  \times  \dfrac{10}{10}\bigg) - \bigg(\dfrac{4}{5}  \times  \dfrac{6}{6}\bigg)  - \bigg( \dfrac{5}{6}  \times  \dfrac{5  }{5} \bigg)+\bigg( \dfrac{7}{10}  \times 3\bigg) - \bigg( \dfrac{1}{12}  \times 15 \times 15\bigg)} = 19}
