Answer 1

3 / 26  ×  4 = ( 3 × 4 ) / 26 = 12 / 26 = ( 12 : 2) / ( 26 : 2) = 6 / 13 

1 / 2  × 4 = ( 1 × 4 ) / 2 = 4 / 2 = 2 

2 / 3  × 4 = ( 2 × 4 ) / 3 = 8 / 3 = 2 intregi si 2 / 3 = 2,(6) 

1 / 8 × 4 = 4 / 8 = ( 4 : 4 ) / ( 8 : 4 ) = 1 / 2 

3 / 4  ×  4 = ( 3 × 4 ) / 4 = 3  → 4 cu 4 se simplifica 

5 / 6  ×  4 = ( 5 × 4 ) / 6 = 20 / 6 = ( 20 : 2) / ( 6 : 2) = 10 / 3 = 3 intregi si 1 / 3

7 / 12  ×  4 = 28 / 12 = ( 28 : 4 ) / ( 12 : 4) = 7 / 3
