Plsss. Va rog !! Repedeee​

Answer 1

Explicație pas cu pas:

a)

$((1 + 2) + ( \frac{7}{12} + \frac{1}{3} )) - ( \frac{9}{4} - \frac{7}{6} ) =$

$(3 + \frac{11}{12} ) - \frac{13}{12} =$

$3 \frac{11}{12} - \frac{13}{12} =$

$\frac{47}{12} - \frac{13}{12} =$

$\frac{17}{6}$

b)

$( \frac{131}{14} - \frac{263}{42} ) - ( \frac{115}{14} - \frac{121}{21} ) =$

$\frac{65}{21} - \frac{103}{42} =$

$\frac{9}{14}$
