a + 4/2 + 5/5 + 3/6 + 6/6 = 5
a + 2 + 1 + 1/2 + 1 = 5
a + 1/2 = 5 - 4
a + 1/2 = 1
2 a + 1 = 2
2 a = 2-1
a = 1/2
a + b + 6/2 + 3/3 + 2/5 + 3/5 = 6
a + b + 3 + 1 + ( 2/5 + 3/5) = 6
a + b = 6 - 4 - 1; deoarece 2/5 + 3/5 = 5/5 = 1
a + b = 1
a = 1/3 , iar b = 2/3; deoarece 1/3 + 2/3 = 3/3 = 1
Observatie Nu exista fractia 0/3, dar daca e trecuta ca piesa de domino, n-am alternativa !
a + 0/2 + 2/2 + 0/3 + 0/4 + 4/4 + 0/5 = 7
a + 1 + 1 = 7
a = 7 - 2
a = 5 = 10/2
