Question

2. If p = 5/6, q = -7/6 and r= 13/16, then verify associative property of addition for these rational numbers.

Answer 1

Answer:

associative property of addition.

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

= 5/6+(-7/6+13/16) = (5/6+ -7/6)+13/16

= 5/6+(-112+78/96)= (30-42/36)+13/16

= 5/6+(-34/96) = (-12/36)+13/16

= (480-204/576) = (-192+468/576)

= 276/576 = 276/576.

hence , verified.
