18 - 1 3/4 = 16 1/4

13 5/15 + 1/6 = 13 10/30 + 5/30 = 13 15/30 = 13 1/2

3 1/8 x 8/11 = 25/8 x 8/11 = 25/11 = 2 3/11

7 - 5/19 = 6 14/19

3/7 + 2 1/3 = 9/21 + 2 7/21 = 2 16/21

6 3/8 x 1/4 = 51/8 x 1/4 = 51/32 = 1 19/32

1 47/51 - 3/51 = 1 44/51

6 3/5 - 2 4/7 = 6 21/35 - 2 20/35 = 2 1/35

3 : 2/5 = 3/1 x 5/2 = 15/2 = 7 1/2

18 - 1 i 3/4 = 17 i 4/4 - 1 i 3/4 = 16 i 1/4

13 i 5/15 + 1/6 = 13 i 10/30 + 5/30 = 13 i 15/30 = 13 i 1/2

3 i 1/8 * 8/11 = 25/8 * 8/11 = 25/11 = 2 i 3/11

7 - 5/19 = 6 i 19/19 - 5/19 = 6 i 14/19

3/7 + 2 i 1/3 = 9/21 + 2 i 7/21 = 2 i 16/21

6 i 3/8 * 1/4 = 51/8 * 1/4 = 51/32 = 1 i 19/32

1 i 47/51 - 3/51 = 1 i 44/51

6 i 3/5 - 2 i 4/7 = 6 i 21/35 - 2 i 20/35 = 4 i 1/35

3 : 2/5 = 3 * 5/2 = 15/2 = 7 i 1/2
