Answer 1

Răspuns:

Explicație pas cu pas:

$\frac{1}{2} + (\frac{1}{2}) : (\frac{1}{3} + \frac{1}{6}) = \\\\\frac{1}{2} + (\frac{1}{2}) : (\frac{2}{6} + \frac{1}{6}) =\\\\\frac{1}{2} + (\frac{1}{2}) : \frac{3}{6} = \\\\\frac{1}{2} + (\frac{1}{2}) * \frac{6}{3} =\\\\\frac{1}{2} + \frac{6}{6} =\\\\\frac{3}{6} + \frac{6}{6} =\\\\\frac{9}{6} = \frac{3}{2}$

$\frac{13}{25} : \frac{26}{75} + (\frac{3}{2})^{2} * \frac{10}{27} =\\\\\frac{13}{25} * \frac{75}{26} + \frac{9}{4} * \frac{10}{27} =\\\\\frac{3}{2} + \frac{5}{6} =\\\\\frac{9}{6} + \frac{5}{6} =\\\\\frac{14}{6} = \frac{7}{3}$
