Ответ:

  1. \[\frac{17}{18}-\frac{10}{18}=\frac{7}{18}.\]
  2. \[5\frac{8}{9}-3=2\frac{8}{9}.\]
  3. \[7\frac{3}{8}-2\frac{1}{8}=5\frac{2}{8}=5\frac{1}{4}.\]
  4. \[6\frac{5}{9}-\frac{4}{9}=6\frac{1}{9}.\]
  5. \[1-\frac{11}{14}=\frac{14}{14}-\frac{11}{14}=\frac{3}{14}.\]
  6. \[6-\frac{3}{19}=5\frac{16}{19}.\]
  7. \[18-5\frac{19}{100}=12\frac{81}{100}.\]
  8. \[1-\frac{10}{23}=\frac{13}{23}.\]
  9. \[\frac{5}{14}-\frac{1}{14}=\frac{4}{14}=\frac{2}{7}.\]
  10. \[5-\frac{7}{9}=4\frac{2}{9}.\]
  11. \[12\frac{3}{10}-\frac{9}{10}=11\frac{13}{10}=11\frac{3}{10}.\]
  12. \[13\frac{7}{17}-9\frac{13}{17}=12\frac{24}{17}-9\frac{13}{17}=3\frac{11}{17}.\]
