Question

Which equation illustrates the commutative property of addition?

1 is A
2 is B
3 is C
4 is D

Answer 1

Option A. 12 + 6 + 15 = 12 + 15 + 6

Explanation:

Cumulative property of addition says if there are three numbers a, b, c then

a + b + c = a + c + b

or a + b + c = c + b + a

Therefore, if three numbers are 12, 6, 15 then

equation that illustrates the commutative property of addition will be

12 + 6 + 15 = 12 + 15 + 6

Option A. 12 + 6 + 15 = 12 + 15 + 6 will be the correct option.

Answer 2

I believe the first one 12+ 6 + 15 = 12 + 15 + 6 is your answer, since you are just moving things around

hope this helps
