Answer 1

a)= 1/4+2 amplificat cu 4+1/2 amplificat cu 2
   =1+8+2/4
   =11/4
b) =4/3 amplificat cu 4+2 amplificat cu 12+9/4 amplificat cu 3
     =16+24+27/12
     =67/12
c) =5 amplificat cu 8+9/8+5/2 amplificat cu 4
    =40+9+20/8
    =69/8
d) =9/4 amplificat cu 3+16/3 amplificat cu 4+ 7/6 amplificat cu 2
    =27+64+14/12
    =105/12
e) =7/6 amplificat cu4+19/8 amplificat cu 3+9/4 amplificat cu 6
    =28+57+54/24
    =139/24
f) = 11/5 amplificat cu 3+1 amplificat cu 15+16/15
   =33+15+16/15
   =64/15
g) =9/7 amplificat cu 2+15/14+1 amplificat cu 14
    =18+15+14/14
    =47/14
h) =13/6 amplificat cu 3+ 7/3 amplificat cu 6+ 28/9 amplificat cu 2
    = 39+42+56/18
    =137/18
i) = 9/4 amplificat cu 3+ 7/12+ 4/3 amplificat cu 4
   =27+7+16/12
   =50/12
