a) \(\frac{3}{14}+(\frac{2}{7}+\frac{1}{2})\) = \(\frac{3}{14}+(\frac{2*2}{7*2}+\frac{1*7}{2*7})\) = \(\frac{3}{14}+(\frac{4}{14}+ \frac{7}{14})\) = \(\frac{3}{14}+\frac{4+7}{14}\) = \(\frac{3}{14}+\frac{11}{14}\) = \(\frac{3+11}{14}\) = \(\frac{14}{14}\) = 1 б) \(\frac{11}{56}+(\frac{6}{7}-\frac{3}{8})\) = \(\frac{11}{56}+(\frac{6*8}{7*8}-\frac{3*7}{8*7})\) = \(\frac{11}{56}+(\frac{48}{56}-\frac{21}{56})\) = \(\frac{11}{56}+\frac{48-21}{56}\) = \(\frac{11}{56}+\frac{27}{56}\) = \(\frac{11+27}{56}\) = \(\frac{38}{56}\) = \(\frac{19}{28}\)
