Porfavor es para mañana

Answer 1

Explicación paso a paso:

a)

$- \frac{5}{3} - ( \frac{1}{3} ) = \\ \\ - \frac{5}{3} - ( \frac{1}{3} ) = - \frac{6}{3} = - 2$

b)

$- \frac{1}{7} \times -( \frac{6}{5 } )^{ - 2} = \\ \\ - \frac{1}{7} \times \frac{25}{36} = - \frac{25}{252}$

c)

$( - \frac{8}{7} - \frac{3}{5} ) \div ( \frac{4}{15} - \frac{2}{3} ) = \\ \\ ( \frac{ - 40 - 21}{35} ) \div ( \frac{4 - 10}{15} ) = \\ \\ - \frac{61}{ 35} \div ( - \frac{6}{15} ) = \\ \\ - \frac{61}{35} \div ( - \frac{2}{5} ) = \frac{305}{70} = \frac{61}{14}$

$d) \\ \frac{5}{7} + \frac{3}{2} \div \frac{1}{7} + \frac{1}{2} = \\ \\ \frac{5}{7} + \frac{21}{2} + \frac{1}{2} = \\ \\ \frac{10 + 147 + 14}{14} = \frac{171}{14}$
