Answer 1

Answer:

$p = \frac{5}{6} , \: q = \frac{( - 7)}{6} , \: r = \frac{13}{16} \\ (p + q) + r = p + (q + r) \\ ( \frac{5}{6} - \frac{7}{6} ) + \frac{13}{16} = \frac{5}{6} + ( \frac{( - 7)}{6} + \frac{13}{16} \\ ( \frac{5 - 7}{6} ) + \frac{13}{16} = \frac{5}{6} + ( \frac{( - 56) + 39}{48} ) \\ \frac{( - 2)}{6} + \frac{13}{16} = \frac{5}{6} + \frac{( - 17)}{48} \\ \frac{( - 16) + 39}{48} = \frac{40 - 17}{48} \\ \frac{23}{48} = \frac{23}{48} \\ LHS=RHS \\ Hence \: verified$

Answer 2

Answer:

No, it is not true.

Step-by-step explanation:

p = 5/6

q = -7/6

r = 13/16

L.H.S = (p+q) + r

         = [5/6 + (-7/6)] + 13/16

         = (-2/6) + 13/16  ( ∵ First we need to solve the bracket and then further)

         = -8/48 + 39/48  (∵ Taking LCM as 48)

         = 31/48

R.H.S = p + (q+r)

         = 5/6 + [(-7/6) + 13/16]

         = 5/6 + [(-56/48) + 39/48]  (∵ taking LCM as 48)

         = 5/6 + (-17/48)

         = 40/48 - 17/48

         = 23/48

Hence LHS ≠ RHS
