Question

Verify the associative property of addition for a = 2/3 , b = 4/5 and c = -5/6

Answer 1

a+(b+c) = (a+b)+c =( a+ c) + b

2/3.+( 4/5 -5/6 )=(2/3. + 4/5) - 5/6

= (2/3. - 5/6) +4/5

2/3 - 1/30 = 22/15. - 5/6. = 4/5. - 3/18

57/90 = 57/90 = 57/90

Answer 2

Step-by-step explanation:

first u have to place everything according to the laws and then take out lcm of A and B in RHS and in LH S

lcm of C and A after completing the bracket now in RHS take lcm of outside the bracket one and same with LHS
