Answer 1

1 supra 2 amplificat cu 7 si 5 supra 7 amplificat cu 2=7 supra 14+10 supra 14=14supra 14 =1 intreg 3/4amplificat cu 11 + 6/11 amplificat cu 4=33/44+24/44=57/44 5/3amplificat 9+4/9amplificat 3=45/27+12/27=57/27 1/2amplificat 3+1/3amplificat 2+1/6=3/6+2/6+1/6=5/6+1/6=6/6=1 2/5amplificat 2 +3/2amplificat 5+7/10=4/10+15/10+7/10=29/10 4/9amplificat cu 2 +1/3 amplificat 6 +7/18=8/18+6/18+7/18=33/18
