Ответ:

1. 1) 2 3/5 - 1 7/10 = 2 6/10 - 1 7/10 = 1 16/10 - 1 7/10 = 9/10

  2) 9/10 + 1 1/2 = 9/10 + 1 5/10 = 2 4/10

  3) 2 4/10 - 7/20 = 2 8/20 - 7/20 = 2  1/20

2. 1) 1/9 * 63 = 7

   2) 2/7 + 7 = 7 2/7

3. 1) 2/9 : 5/48 = 2/9 * 48/5 = 2 2/15

   2) 11/18 + 2 2/15 = 55/90 + 2 12/90 = 2 67/90

4. 1) 3 1/7 : 11/14 = 22/7 * 14/11 = 4

5. 1) 5 2/3 : 1/3 = 17/3 * 3/1 = 17

   2) 1 7/12 * 6 = 19/12 * 6 = 9 1/3

   3) 17 - 9 1/3 = 16 3/3 - 9 1/3 = 7 2/3

6. 1) 2 2/15 * 3 1/8 = 32/15 * 25/8 = 20/3

   2) 20/3 * 9/14 = 30/7

   3) 9 - 4 2/7 = 8 7/7 - 4 2/7 = 4 5/7
