Resolução,

$\mathsf{\Big[\Big(2 + \dfrac{3}{5}\Big)\cdot \dfrac{15}{13} - \dfrac{1}{8} : \Big(- \dfrac{3}{4}\Big)\Big]\cdot \dfrac{12}{19}}$

$\mathsf{\Big[\Big(\dfrac{13}{5}\Big)\cdot \dfrac{15}{13} + \dfrac{4}{24}\Big]\cdot \dfrac{12}{19}}$

$\mathsf{\Big[\dfrac{195}{65} + \dfrac{4}{24}\Big]\cdot \dfrac{12}{19}}$

$\mathsf{\Big[3 + \dfrac{4}{24}\Big]\cdot \dfrac{12}{19}}$

$\mathsf{\dfrac{76}{24}\cdot \dfrac{12}{19}}$

$\mathsf{\dfrac{912}{456}}$

$\boxed{\mathsf{= 2}}$
