Question

ayuden me (3)(1/8)/(-2.5)

Answer 1

$\left(3\right)\frac{\left(\frac{1}{8}\right)}{\left(-2.5\right)}$
$\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{\frac{b}{c}}{a}=\frac{b}{c\:\cdot \:a}$
$3*(-\frac{1}{8*\:2.5})$
$=3\left(-\frac{1}{20}\right)$
$\mathrm{Multiplicar\:fracciones}:\quad \:a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}$
$\mathrm{Quitar\:los\:parentesis}:\quad \left(-a\right)=-a$
$=-\frac{3\cdot \:1}{20}$
$=-\frac{3}{20}$
$=-0.15$
