b) 5/6
c) 8/30
d) 21/30
e) 7/10

Answer 1

Resposta:

E

Explicação passo-a-passo:

$\frac{5}{9} \times \frac{6}{4} - \frac{4}{9} \div \frac{10}{3} = \\ \\ \frac{30}{36} - \frac{4}{9} \times \frac{3}{10} = \\ \\ \frac{30}{36} - \frac{12}{90} = \\ \\ \frac{5}{6} - \frac{4}{30} = \\ \\ \frac{25 - 4}{30} = \frac{21}{30} = \frac{7}{10}$
