Question

120:(-60)-(-9)-{14:[-2(+5)]}+(-30)

Answer 1

Respuesta:

El resultado es  $-\frac{108}{5}.$

Explicación paso a paso:

$120\div \left(-60\right)-\left(-9\right)-14\div \left[-2\left(+5\right)\right]+\left(-30\right)$

$\frac{120}{-60}-\left(-9\right)-\frac{14}{-2\left(5\right)}+\left(-30\right)$

$\frac{120}{-60}+9-\frac{14}{-2\cdot \:5}-30$

$-\left(-\frac{7}{5}\right)-2+9-30$

$\frac{7}{5}-2+9-30$

$\frac{7}{5}-23$

$\mathrm{Convertir\:a\:fraccion}:\quad \:23=\frac{23\cdot \:5}{5}$

$-\frac{23\cdot \:5}{5}+\frac{7}{5}$

$\frac{-23\cdot \:5+7}{5}$

$\frac{-108}{5}=-\frac{108}{5}$
