Which property is illustrated?

18 + 9 = 9 + 18

distributive property
associative property of addition
identity property of addition
commutative property of addition

Option D- Commutative property of addition.

18 + 9 = 9 + 18 which illustrate commutative property of addition.

Solution:

Step 1:

The given data is a commutative property of addition, because no-matter where we put the numbers, you will always get the same answer. This can be represented by a + b = b+ a

Step 2:

From the given Data

18 + 9 = 9 + 18  

When we add LHS and RHS we get the same answer 27.

Step 3:

If we exchange the numbers in this problem then also you will get the same answer.

9 + 18 = 18 + 9 which gives 27.  

Result:

Hence we come to the conclusion; the given data illustrates commutative property of addition.
