Explicație pas cu pas:
11 / 14; 5 / 8; 17 / 28
__________________
14 = 2 x 7
8 = 2³
28 = 2² x 7
__________
c.m.m.m.c al numitorilor ( 14, 8 si 28 ) = 8 x 7 = 56
_________________________________________
( 11 x 4 ) / ( 14 x 4 ) = 44 / 56 → am amplificat fractia( 11 / 14 ) cu 4
( 5 x 7 ) / ( 8 x 7 ) = 35 / 56 → am amplificat fractia ( 5 / 8 ) cu 7
( 17 x 2 ) / ( 28 x 2 ) = 34 / 56 → am amplificat fractia ( 17 / 28 ) cu 2
