Resposta:

a) 4/3

b) 0

Explicação passo-a-passo:

a)2/3 : 4/5 +1/2

\frac{\frac{2}{3} }{\frac{4}{5} } +\frac{1}{2} \\\\\frac{2}{3} . \frac{5}{4} + \frac{1}{2}\\\\\frac{10}{12} +\frac{1}{2} \\\\\frac{10}{12}  + \frac{6}{12}\\\\\frac{16}{12} \\\\\frac{4}{3}

b)1/2 - 5/8 : 5/4​

\frac{1}{2} - \frac{\frac{5}{8}}{\frac{5}{4}} \\\\\frac{1}{2} - \frac{5}{8} . \frac{4}{5} \\\\\frac{1}{2} - \frac{20}{40}\\\\\frac{20}{40} - \frac{20}{40}\\\\0
