  2. 10 1/4 : 5 = (10 + 1/4) : 5 = 10 : 5 + 1/4 : 5 = 2 + 1/20 = 2 1/20.

  3. 27 9/11 : 9 = (27 + 9/11) : 9 = 27 : 9 + 9/11 : 9 = 3 + 1/11 = 3 1/11.

  4. 2 1/5 : 1/5 = (2 + 1/5) : 1/5 = 2 : 1/5 + 1/5 : 1/5 = 10 + 1 = 11.

  5. 4 2/3 : 1/9 = (4 + 2/3) : 1/9 = 4 : 1/9 + 2/3 : 1/9 = 36 + 6 = 42.

  6. 1 5/7 : 1/3 = (1 + 5/7) : 1/3 = 1 : 1/3 + 5/7 : 1/3 = 3 + 15/7 = 5 1/7.

  7. 2 1/4 : 3/5 = (2 + 1/4) : 3/5 = 2 : 3/5 + 1/4 : 3/5 = 10/3 + 5/12 = 15/4 = 3 3/4.
