Пошаговое объяснение:

$1-\frac{4}{9} =\frac{9}{9} -\frac{4}{9} =\frac{5}{9}$

$8\frac{8}{15} -4\frac{9}{20} =\frac{128}{15} -\frac{89}{20} =\frac{512}{60} -\frac{267}{60} =\frac{245}{60} =\frac{49}{12} =4\frac{1}{12}$

$4-3\frac{3}{4}=\frac{16}{4} -\frac{15}{4} =\frac{1}{4}$

$9\frac{4}{21} -4\frac{11}{14} =\frac{193}{21} -\frac{67}{14} =\frac{386}{42} -\frac{201}{42} =\frac{185}{42} =4\frac{17}{42}$

$7\frac{1}{10} -3\frac{1}{6} =\frac{71}{10} -\frac{19}{6} =\frac{213}{30} -\frac{95}{30} =\frac{118}{30} =\frac{59}{15} =3\frac{14}{15}$

$5\frac{5}{33} -4\frac{7}{22} =\frac{170}{33} -\frac{95}{22} =\frac{340}{66} -\frac{285}{66} =\frac{55}{66}=\frac{5}{6}$
