Question

Verify the associative property of addition for the following sets of rational numbers:2/9,-1/3,-3/5.

Answer 1

Step-by-step explanation:

adding 2/9 and -1/3 first,, then adding -3/5 on LHS

adding -1/3 and -3/5 first,, then adding 2/9 on RHS

both will give same results

LHS=RHS

hence verified

Answer 2

Answer:

According to associative property:

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

Step-by-step explanation:

Verification:-

Let a= 2/9

b= -1/3

c= -3/5

Let us solve this by putting (a+b)+c on the L.H.S and a+(b+c) on the R.H.S

According to question:-

L.H.S

(a+b)+c

={(2/9 +(-1/3)}+(-3/5)

=0.71

R.H.S

a+(b+c)

=2/9+{(-1/3) + (-3/5)}

=0.71

Since L.H.S = R.H.S,

HENCE PROVED ADDITION OF RATIONAL NUMBERS IS ASSOCIATIVE
