Question

Efectuati 1/6+1/6:1/3

Answer 1

1/6+1/6x3

1/6+1/2

=2/3

Answer 2

1/6 + 1/6 : 1/3 = 1/6 + 1/6 × 3/1 = 1/6 + 1/2 = 1/6 + 3/6 = 4/6 = 2/3 

          → am simplificat pe 3 cu 6 prin 3 = 1/2 
          → am adus fractia 1/2 la acelasi numitor 6, amplificand-o cu 3 
          → am adunat numaratorii;
          → am simplificat pe 4/6 prin 2 = 2/3
