Answer 1

Resposta:

Explicação passo-a-passo:

A)

$\frac{12}{5} ÷2 + \frac{1}{4} x \frac{7}{5} - \frac{2}{3}$

$\frac{12}{5} x \frac{1}{2}+\frac{7}{20} -\frac{2}{3}$ (simplifique o 12 e 2 dividindo por 2)

$\frac{6}{5} + \frac{7}{20} - \frac{2}{3}$ (mmc de 5, 21, 40 = 60)

$\frac{72+21-40}{60}$

$\frac{53}{60}$

B)

[($\frac{2}{6}+\frac{4}{6})÷\frac{1}{3}+\frac{2}{8}]x\frac{16}{13}$

$(1$÷$\frac{1}{3}+\frac{2}{8})$×$\frac{16}{13}$

(3+ $\frac{2}{8}$)×$\frac{16}{13}$

$\frac{14}{4}$×$\frac{16}{13}$

$\frac{208}{52}$  (simplifica por 52)

$\frac{4}{1}$
