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:
-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.
