Answer 2

Explicație pas cu pas:

$a = [0,(2) - \dfrac{1}{4} : 0,25 + {3}^{ - 3} ] \cdot 0,27 =$

$= \bigg( \frac{2}{9} - \dfrac{1}{4} : \dfrac{25}{100} + \dfrac{1}{ {3}^{3} } \bigg) \cdot \dfrac{27}{100}$

$= \bigg( \frac{2}{9} - \dfrac{1}{4} : \dfrac{1}{4} + \dfrac{1}{27} \bigg) \cdot \dfrac{27}{100}$

$= \bigg( \frac{^{3)} 2}{9} - ^{27)} 1 + \dfrac{1}{27} \bigg) \cdot \dfrac{27}{100}$

$= \dfrac{6 - 27 + 1}{27} \cdot \dfrac{27}{100} = - \dfrac{20}{27} \cdot \dfrac{27}{100}$

$= - \dfrac{1}{5}$
