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
