Пошаговое объяснение:

$(\frac{11}{35} +\frac{3}{14} )-\frac{6}{35} =\frac{5}{14} \\\\\frac{11}{35} +\frac{3}{14} =\frac{22}{70} +\frac{15}{70} =\frac{37}{70} \\\\\frac{37}{70} -\frac{6}{35} =\frac{37}{70} -\frac{12}{70} =\frac{25}{70} =\frac{5}{14}$

$\frac{17}{39} -(\frac{4}{39} +\frac{1}{9} )=\frac{2}{9} \\\\\frac{4}{39} +\frac{1}{9} =\frac{12}{117} +\frac{13}{117} =\frac{25}{117} \\\\\frac{17}{39} -\frac{25}{117} =\frac{51}{117} -\frac{25}{117} =\frac{26}{117} =\frac{2}{9}$
