Answer 1

a)3/5•(1/2 - 3/2)=3/5•(-1)=(-3/5)

b)1,5•(-5,1-4,2-3,3)=1,5•(-12,6)=(-18,9)

c)(1 + 1/3)•(8,3-2,3)=4/3•6=8

d)4/9•(1 - 1/5 - 7/10)=4/9•1/10=2/45

Answer 2

Răspuns:

3/5(1/2-3/2=3/5×(-1)=-3/5 ;  b)                  1,5(-5,1-4,2-3,3)= 1,5×(-12,6)=-18,9 ;     c)  

4/3(8,3-2,3)=4/3×6 =8 ;   d)    4/9(1-1/5-7/10)=4/9(10/10-2/10-7/10)=4/9×1/10=2/45
