8 9 -- + -- == 1 26 13Similarly, the 3-fractions puzzle has a unique result up to symmetry:
5 7 9 -- + -- + -- == 1 34 68 12Some of the many solutions to the 4-fractions puzzle are:
1 3 8 9 -- + -- + -- + -- == 1 24 56 14 27 1 5 7 8 -- + -- + -- + -- == 1 39 26 42 13 1 3 6 9 -- + -- + -- + -- == 1 52 78 24 13Some of the many solutions to the 5-fractions puzzle are:
1 5 8 9 9 -- + -- + -- + -- + -- == 1 12 45 36 27 36 1 6 7 8 9 -- + -- + -- + -- + -- == 1 12 45 35 24 36 1 7 8 9 9 -- + -- + -- + -- + -- == 1 12 56 48 24 36Some of the many solutions to the 6-fractions puzzle are:
1 2 4 5 8 9 -- + -- + -- + -- + -- + -- == 1 12 33 45 77 68 69 1 2 4 5 7 8 -- + -- + -- + -- + -- + -- == 1 12 33 45 78 69 69 1 2 5 5 6 6 -- + -- + -- + -- + -- + -- == 1 12 33 49 79 78 84
