Answer 1

D) $\frac{3}{5} + \frac{1}{4} . \frac{3}{5} - (\frac{1}{2})^{3} + \sqrt\frac{49}{100} + \frac{1}{4}$

$\frac{3}{5} + \frac{1}{4} . \frac{3}{5} -\frac{1}{8} + \frac{7}{10} + \frac{1}{4}$

Tira-se o MMC = 40.

$\frac{24 + 10 . 24 - 5 + 28 + 10}{40}$

$\frac{24 + 240 - 5 + 28 + 10}{40}$

$\frac{24 + 240 - 5 + 28 + 10}{40} = \frac{297}{10}$

E) $\sqrt\frac{121}{4} / \frac{5}{3} + (\frac{3}{2})^{2}  + \frac{1}{2}$

$\frac{11}{2} / \frac{5}{3} + \frac{9}{4}  + \frac{1}{2}$

Tira-se o MMC = 12,

$\frac{66 / 20 + 27 + 6}{12}$

$\frac{3,3 + 27 + 6}{12} = \frac{36,3}{12}$
