Which property would allow you to use mental computation to simplify the problem 27 + 15 + 3 + 5? additive identity additive inverse commutative property of addition distributive property

The property is commutative property of addition ⇒ 3rd answer

Step-by-step explanation:

* Lets explain the commutative property of addition

- The commutative property of addition means changing the order

 of the numbers we are adding without changing the result of adding

- Ex: 2 + 1 + 3  can be written as  3 + 2 + 1 without changing the sum

 of the numbers

* Lets solve the problem

- We want to use the mental computation to simplify the problem

  27 + 15 + 3 + 5

∵ It is easy to find the sum of 27 and 3

∵ It is easy to find the sum of 15 and 5

∴ We want to re-arrange the places of the numbers

∴ 27 + 15 + 3 + 5 could be written 27 + 3 + 15 + 5

∵ The sum of 27 + 15 + 3 + 5 = 50

∵ The sum of 27 + 3 + 15 + 5 = 50

∴ There is no change in the result of the addition

∵ The commutative property of addition means changing the order

  of the numbers we are adding without changing the result of adding

∴ The property is commutative property of addition
