Question

-2×[3-(-6):(-9)]-2×[5-(-7)] =?

Answer 1

Răspuns:

$\frac{58}{3}$

Explicație pas cu pas:

-2×[3-6×$\frac{1}{9}$]-2×(5+7)=

-2×(3-$\frac{6}{9}$)-2×12=

-2×($\frac{27}{9}$-$\frac{6}{9}$)-2×12=

-2×($\frac{27-6}{9}$)-24=

-2×$\frac{21}{9}$-24=

-$\frac{2×21}{9}$-$\frac{24×9}{9}$=

-$\frac{42-216}{9}$=

-$\frac{-174}{9}$=

$\frac{174}{9}$=

$\frac{58}{3}$
