Answer 1

Resposta:

a)

$\frac{5}{8} + \frac{1}{2} - \frac{2}{3}$

$\frac{15 + 12 - 16}{24}$

$\frac{11}{24}$

b)

$(\frac{1}{3} )^{2} + \frac{2}{5} \times \frac{1}{2}$

$\frac{1}{9} + \frac{2}{5} \times \frac{1}{2}$

$\frac{1}{9} + \frac{1}{5}$

$\frac{14}{45}$

c)

$\frac{1}{2} \div ( \frac{2}{3} + \frac{3}{4} )$

$\frac{1}{2} \div \frac{17}{12}$

$\frac{1}{2} \times \frac{12}{17}$

$\frac{6}{17}$

d)

$(3 \times \frac{5}{2}) \div ( \frac{1}{5} + \frac{1}{3} )$

$\frac{15}{2} \div \frac{8}{15}$

$\frac{15}{2} \times \frac{15}{8}$

$\frac{225}{16}$

e)

$(1 + \frac{1}{3} )^{2} \times \frac{9}{4} + 6$

$(\frac{1}{3})^{2} \times \frac{9}{4} + 6$

$\frac{1}{9} \times \frac{9}{4} + 6$

$\frac{1}{4} + 6$

$\frac{25}{4}$
