Question

Verify the commutative law or addition
the following pairs of rational numbers -1/3 -2/5​

Answer 1

Answer:

Step-by-step explanation:

Case 1

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

= -5 - 6/15

= -11/15

Case 2

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

= -6 - 5/15

= -11/15

Hence the commutative property for addition is verified.

Answer 2

Answer:

-1/3 + -2/5

Step-by-step explanation:

Commutative property= x+y=y+x

=Lcm of 3 and 5 is 15

So, we will multiply -1and 3 by 5

and -2/5 by 3

=-1/3×5,-2/5×3

=-5/15+-6/15

=-11/15

-2/5×3,-1/3×5

-5/15+-6/15

-11/15

So, the sum is same when we change the order. So verified that x+y=y+x.
