Answer 1

Answer:

7/12=7/12 . RHS=LHS

Step-by-step explanation:

1/2 +[3/4+(-2/3)] = [1/2+3/4]+(-2/3)

1/2 +[(9-8)/12] =  [(2+3)/4} - 2/3

1/2 + 1/12 = [ 5/4] - 2/3

(6+1)/12 = (15-8)/12

7/12 = 7/12        

Answer 2

Answer:

both have answer=8/6

Step-by-step explanation:

a+(b+c)

1/2+(3/2+(-2)/3)

L.C.M of denominators (2,2,3)=6

3+(9+ -4)= 3+5= 8

6 6 6

(a+b)+c

(1/2+3/2)+(-2)/3

L.C.M of denominators (2,2,3)=6

(3+9)+ -4 = 12+-4= 8

6 = 6 6

so answers are same

it means a+(b+c)=(a+b)+c
