Answer 1

Answer:

put the values , its simple

Step-by-step explanation:

p+q+r=p+q+r

this is what the question says

this is associative property

Answer 2

Given:

p = -4/9

q = 2/3

r = 8/11

To verify:

p + (q + r) = (p + q) + r

Verification:

LHS = p + (q + r)

       = -4/9 + (2/3 + 8/11)

       = -4/9 + 46/33

       = -132 + 414/297

       = 282/297

RHS = (p + q) + r

       = (-4/9 + 2/3) + 8/11

       = 6/27 + 8/11

       = 66 + 216/297

       = 282/297

∴ LHS = RHS

Hence, verified.

Hope it helps!!!
