Question

(-3/2-4/5)+(7/3+5/2)


(-6/4+3/2)-(6/5+4/3)

Answer 1

Respuesta:

$( - \frac{3}{2} - \frac{4 }{5} ) + ( \frac{7}{3} + \frac{5}{2} ) \\ \\ ( \frac{ - 15 - 8}{10} ) + ( \frac{14 + 15}{6} ) \\ \\ - \frac{23}{10} + \frac{29}{6} = \frac{ - 138 + 290}{60} = \\ \\ \frac{152}{60} simplificamos \: y \: queda \: \frac{38}{15}$

$( - \frac{6}{4} + \frac{3}{2} ) - ( \frac{6}{5} + \frac{4}{3} ) \\ \\ ( \frac{ - 24 + 6}{4} ) - ( \frac{18 + 20}{15} ) \\ \\ - \frac{18}{4} - \frac{38}{15} = \frac{ - 270 - 152}{60} = \\ \\ - \frac{422}{60} = simplificamos \: y \: nos \: \\ queda \: - \frac{211}{30}$
