Question

Va rog URGENT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

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
