Explicação passo-a-passo:

$\dfrac{2}{3} : \dfrac{5}{8} + \dfrac{1}{2}$

$\dfrac{2}{3} \times \dfrac{8}{5} + \dfrac{1}{2}$

$\dfrac{16}{15} + \dfrac{1}{2}$

$\dfrac{16}{15} + \dfrac{1}{2}$

$\boxed{\boxed{\dfrac{47}{30}}}$

$\dfrac{1}{2} - \dfrac{5}{8} : \dfrac{5}{4}$

$\dfrac{1}{2} - \dfrac{5}{8} \times \dfrac{4}{5}$

$\dfrac{1}{2} - \dfrac{1}{2}$

$\boxed{\boxed{0}}$
