Answer 2

Explicație pas cu pas:

$1 - \frac{1}{2} : \Big(1 - \frac{1}{2} \Big) \cdot \Big[- \frac{1}{4} + (-4) \cdot \Big( \frac{1}{3} + \frac{1}{3} : (-2))\Big)\Big] + \frac{1}{13} =$

$= 1 - \frac{1}{2} : \frac{1}{2} \cdot \Big[- \frac{1}{4} - 4 \cdot \Big( \frac{1}{3} - \frac{1}{6})\Big)\Big] + \frac{1}{13}$

$= 1 - 1 \cdot \Big(- \frac{1}{4} - 4 \cdot \frac{1}{6}\Big) + \frac{1}{13}$

$= 1 - \Big(- \frac{^{3)} 1}{4} - \frac{^{4)}2}{3}\Big) + \frac{1}{13}$

$= 1 - \Big(- \frac{3 + 8}{12}\Big) + \frac{1}{13}$

$= ^{156)} 1 + \frac{^{13)} 11}{12} + \frac{^{12)} 1}{13}$

$= \frac{156 + 143 + 12}{156}$

$= \frac{311}{156} = 1 \frac{155}{156}$
