Answer 1

Explicação passo-a-passo:

$\frac{1}{2} + \frac{3}{4} \times \frac{2}{5} \div \frac{1}{3} \\ \frac{1}{2} + \frac{6}{20} \div \frac{1}{3}$

$\frac{1}{2} + \frac{18}{20} \\ \frac{1}{2} + \frac{9}{10} \\ \frac{5 + 9}{10} = \frac{14}{10} = \frac{7}{5}$

Answer 2

Resposta:

d) 7/5

Explicação passo-a-passo:

1/2 + 3/4 × 2/5 ÷ 1/3

1/2 + 6/20 ÷ 1/3

1/2 + 18/20

28/20

28/20 = 14/10 = 7/5
