Ответ:

  1. \(3\frac{1}{16}-\frac{1}{8}=3\frac{1}{16}-\frac{2}{16}=3\frac{15}{16}\).
  2. \(7\frac{17}{20}-5\frac{17}{30}=2+\frac{51-34}{60}=2\frac{17}{60}\).
  3. \(4\frac{2}{7}-1\frac{4}{9}=3+\frac{18-28}{63}=2\frac{53}{63}\).
  4. \(8\frac{5}{36}-1\frac{43}{108}=7+\frac{15-43}{108}=7\frac{20}{27}\).
  5. \(9\frac{7}{9}-4\frac{5}{6}=5+\frac{14-15}{18}=4\frac{17}{18}\).
  6. \(6\frac{7}{32}-2\frac{11}{48}=4+\frac{21-22}{96}=3\frac{95}{96}\).
