Explicație pas cu pas:
a) (-7/3)*(-60/35)=4
dupa simplificare cu 7,5,3
(-)*(-)=+
f) (-8/5) -(18/12) =
-8/5-3/2 ,aducem la acelasi numitor si calculam
( -16-15) /10=-31/10=-3,1
b)0,(5)=5/9
2 1/3=(2*3+1)/3=7/3
5/9*7/3*18/5=14/3
c) 2/9*(-8+5)/6=2/9*(-1/2)=-1/9
d) 11/12+(5/12)-7/24=16/12-7/24=(32-7)/24=25/24
e) 3/4*(-5/3)=-5/4
