Question

verify (a+b)+c=a+(b+c) by taking a= -2/3, b=5/6 and c= -5/8

Answer 1

(a+b) +c=a+(b+c) [ASSOCIATE PROPERTY OF ADDITION)]

A=-2/3
B=5/6
C=-5/8

[-2/3+5/6]+-5/8≠a+(b+c) as a and c are negative and associative property does not hold true under subtraction.

Answer 2

Hi Friend !!!!


Here is ur answer !!!

a = -2/3

b = 5/6

c = -5/8

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

=> (-2/3 + 5/6) + -5/8 = -2/3 +(5/6+-5/8)

=> (-4+5/6)+-5/8 = -2/3 +(20-15/24)

=>(1/6)-5/8 = -2/3 + 5/24

=>1/6 + -5/8 = -16+5/24

=> 4-15 / 24 = -11/24

=> -11/24 = -11/24


Hope it helps u : )
