Ответ:

  1. \(4\frac{11}{12}+3\frac{5}{12}=7\frac{16}{12}=8\frac{1}{3}\).
  2. \(4\frac{11}{12}+3=7\frac{11}{12}\).
  3. \(\frac{11}{12}+\frac{5}{12}=\frac{16}{12}=1\frac{1}{3}\).
  4. \(4+\frac{5}{12}=4\frac{5}{12}\).
  5. \(\frac{11}{12}+3=3\frac{11}{12}\).
  6. \(4\frac{11}{12}+\frac{5}{12}=4+\frac{16}{12}=5\frac{1}{3}\).
  7. \(4+3\frac{5}{12}=7\frac{5}{12}\).
  8. \(\frac{11}{12}-\frac{5}{12}=\frac{6}{12}=\frac{1}{2}\).
  9. \(4\frac{11}{12}-\frac{5}{12}=4\frac{6}{12}=4\frac{1}{2}\).
  10. \(4\frac{11}{12}-3\frac{5}{12}=1\frac{6}{12}=1\frac{1}{2}\).
  11. \(4\frac{11}{12}-3=1\frac{11}{12}\).
