Rezolvare :
$e) \frac{13}{20} + \frac{1}{2} - ( \frac{1}{4} + \frac{1}{5} ) = \frac{13}{20} + \frac{1}{2} - \frac{9}{20} = \frac{7}{10} = 0.7$
$h)2 - ( \frac{13}{8} - \frac{1}{3} ) - ( \frac{3}{4} - \frac{5}{12} ) = 2 - \frac{31}{24} - \frac{1}{3} = \frac{3}{8} = 0.375$
$k) \frac{13}{10} - \frac{7}{20} - ( \frac{1}{5} + \frac{1}{4} ) = \frac{13}{10} - \frac{70}{20} - \frac{9}{20} = - \frac{ 53}{20} = - 2.65$
$n) \frac{4}{5} + \frac{7}{8} - ( \frac{1}{2} - \frac{1}{4} + \frac{1}{5} - \frac{1}{10} ) = \frac{4}{5} + \frac{7}{8} - \frac{7}{20} = \frac{53}{40} = 1.325$
