Question

1/2,-2/3,1/5 verify by associative law of addition​

Answer 1

Step-by-step explanation:

First try to understand the Associative Law (Property) of Addition

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

See the SOLUTION :-

{(1/2) + (-2/3) } +(1/5) = (1/2) + {(-2/3) +(1/5) }

=> { (1/2) - (2/3) } + 1/5 = 1/2 + { - 2/3 + 1/5 }

=> (1/2 -2/3) + 1/5 = 1/2 + ( - 10+ 3)/15

=> ( 3-4)/6 + 1/5 = 1/2 + ( - 7)/15

=> - 1/6 + 1/5 = 1/2 - 7 /15

=> (- 5 +6) /30 = (15- 14)/30

=> 1/30 =1/30

Hence LHS = RHS (Proved)
