Question

use rational number (-4/5), (7/10) and (-11/20) to verify associative property of additional of rational numbers​

Answer 1

Answer:

Step-by-step explanation:

Associative Property = a/b + (c/d + e/f) = (a/b + c/d) + e/f

= -4/5 + (7/10 - 11/20) = (-4/5 + 7/10) - 11/20

= -4/5 + (14 - 11 / 20) = (-8 + 7/10) - 11/20

= -4/5 + (13/20) = (-1/10) - 11/20

= -4/5 + 13/20 = -1/10 - 11/20

= -12 + 13/20 = 2 - 11 /20

= -25/20 = 9/20

= 5/4 ≠ 9/20

     ∴ LHS ≠ RHS
