Question

2/9-[5/4+(7/5.3/2)]2/3​

Answer 1

Respuesta:

-1.19951\dots

Explicación paso a paso:

\mathrm{Quitar\:los\:parentesis}:\quad \left(a\right)=a

=\frac{\frac{2}{9}-\left(\frac{5}{4}+\frac{\frac{7}{5.3}}{2}\right)\cdot \:2}{3}

=\frac{\frac{2}{9}-2\left(\frac{5}{4}+\frac{7}{10.6}\right)}{3}

\mathrm{Dividir:}\:\frac{7}{10.6}=0.66037\dots

=\frac{\frac{2}{9}-2\left(\frac{5}{4}+0.66037\dots \right)}{3}

simplificar

=\frac{-3.59853\dots }{3}

\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{-a}{b}=-\frac{a}{b}

=-\frac{3.59853\dots }{3}

\mathrm{Dividir:}\:\frac{3.59853\dots }{3}=1.19951\dots

=-1.19951\dots
