Question

If a, b and c are whole number verify (a+b)+c=a+(b+c),taking a=10,b=7andc=5

Answer 1

Answer:

a + ( b + c ) = ( a + b ) + c      [ Commutative Property of Addition ]

Substituting: a = 10, b = 7, c = 5 we get,

⇒ 10 + ( 7 + 5 ) = ( 10 + 7 ) + 5

Solving the sum in brackets first we get,

⇒ 10 + 12 = 17 + 5

=> 22 = 22

LHS = RHS

Hence Verified !!

Answer 2

Given-


a=10
b=7
c=5

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


by putting the values



(10+7)+5=10+(7+5)

17+5=10+12


22=22




hence, the number verified is whole number.
