Question

Resolver los siguiente ejercicio

Answer 1

Explicación paso a paso:

c

$( \frac{ - 3}{2} - \frac{4}{5} ) + ( \frac{7}{3} + \frac{5}{2} )$

$\frac{ - 15 - 8}{10} + \frac{14 + 15}{6}$

$\frac{ - 23}{10} + \frac{29}{6} = \frac{ - 69 + 145}{30} = \frac{76}{30} simplificar \frac{38}{15}$

d

$( \frac{ - 6}{4} + \frac{3}{2} ) - ( \frac{6}{5} + \frac{4}{3} )$

$\frac{ - 6 + 6}{4} - \frac{18 + 20}{15} =$

$\frac{0}{4} - \frac{38}{15} = \frac{0 - 152}{60} = \frac{ - 152}{60} simplifica \frac{ - 38}{15}$

e

$(\frac{ - 9}{4} \times \frac{2}{5}) + ( \frac{ 7}{10} \times \frac{4}{2} )$

$\ \frac{ - 18}{20} + \frac{28}{20} = \frac{10}{20} simplificar \frac{1}{2}$

f

$( \frac{ - 2}{5} \div \frac{6}{7} ) - ( \frac{4}{3} \div \frac{1}{8} )$

$\frac{ - 14}{30} - \frac{32}{3}$

$\frac{ - 14 - 320}{30} = \frac{ - 334}{30}$
