Option D- Commutative property of addition.
Answer:
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.
