Answer 1

Respuesta:

a)

$- \frac{5}{2} \times \frac{4}{4} \times (- \frac{1}{6} ) = \\ \frac{20}{48} = \frac{5}{12}$

b)

$\frac{1}{2} - \frac{3}{5} + \frac{2}{7} = \frac{35}{70} - \frac{17}{70} + \frac{20}{70} = \frac{38}{70} = \frac{19}{35}$

c)

$\frac{10}{7} \div ( - \frac{8}{3} ) = \\ \frac{10}{7} \times ( - \frac{3 }{8} ) = - \frac{30}{56} = \frac{15}{28}$

d)

$\frac{2}{7} + \frac{2}{7} + \frac{2}{7} = \frac{6}{7}$
