9/20 + 2/4 + 3/5

= 9/20 + 10/20 + 12/20

= 31/20

= 1 11/20

8/40 + 2/8 + 3/4

= 8/40 + 10/40 + 30/40

= 48/40

= 1 8/40

= 1 1/5

5/20 + 2/4 + 3/5

= 5/20 + 10/20 + 12/20

= 27/20

= 1 7/20

5/12 + 3/6 + 5/4

= 5/12 + 6/12 + 15/12

= 26/12

= 2 2/12

= 2 1/6

5/18 + 2/6 + 3/9

= 5/18 + 6/18 + 6/18

= 17/18

5/14 + 2/7 + 3/4

= 10/28 + 8/28 + 21/28

= 39/28

= 1 11/28
