(+13 supra 18)+(-5 supra 6)
(-7 supra 12)+(-3 supra 4)repede Va rog ajutati-ma ! dau coroana!

Answer 1

/=supra
-4/9 +1/9=-3/9(se simplifica prin 3)=-1/3
-5/8+1/8=-4/8=(se simplifica prin 4)=-1/2
-9/11 (se aplifica cu 14) +(-5/9)(se aplifica cu 11)=-144-55/154=-199/154
(1/6)×2+(-3/4)×3=2/12+-9/12=-7/12
(-5/6)×4+(3/8)×3=-20+9/24=-11/24
(-1/6)×2+5/12=3/12(:3)=1/3
13/18+(-5/6)×3=13-15/18=-2/18(:2)=-1/9
-7/12+(-3/4)×3=-7-9/12=-16/12(:4)=-4/3
Sper ca team ajutat
