Question

Stella rewrites −212+3.7 as 3.7−212. Which property did she use? A. Additive Identity Property B. Additive Inverse Property C. Commutative Property D. Distributive Property

Answer 1

Option C.

Explanation:

It is given that Stella rewrites −212+3.7 as 3.7−212.

We need to find which property did she use.

According to commutative property of addition,

`A+B=B+A`

Where, A and B are any real values.

In the given expression −212+3.7, A=-212 and B=3.7.

Using commutative property of addition, we get

`(-212)+3.7=3.7+(-212)`

`(-212)+3.7=3.7-212`

So, she used commutative property.

Therefore, the correct option is C.
