[(-8)96: 2106 +(-9)54 : 3106 +(-5): 2523 ]: 2×3​

Answer 1

Răspuns:

[(-8)×96:2106+(-9)×54:3106+(-5):2523]:2×3=

$( - \frac{8 \times 96}{2106} - \frac{9 \times 54}{3106} - \frac{5}{2523} ) \frac{1}{2} \times 3 =$

$( - \frac{4 \times 96}{1053} - \frac{9 \times 27}{1553} - \frac{5}{2523} ) \times \frac{1}{2} \times 3 =$

$( - \frac{4 \times 32}{351} - \frac{243}{1553} - \frac{5}{2523} ) - \frac{1}{2} \times 3 =$

$( - \frac{128}{351} - \frac{243}{1553} - \frac{5}{2523} ) \times \frac{1}{2} \times 3 =$

$- \frac{ 239817262}{458431623} \times \frac{1}{2} \times 3 =$

$- \frac{119908631}{152810541}$

$= - 0.784688$
