Which is an example of the associative property?

–(18.9 + 3.2) = –18.9 + (–3.2)

–5.5 + 7.9 = 7.9 + (–5.5)

–17.5 + 0 = –17.5

(8.4 + 10.3) + (–4.1) = 8.4 + (10.3 + (–4.1))

Solution:

Given that we have to find the associative property of addition

When we add, we can group the numbers in any combination

Option A

–(18.9 + 3.2) = –18.9 + (–3.2)

Here, negative sign outside the bracket is distributed to terms inside the bracket

This is not a example of associative property

Option B

–5.5 + 7.9 = 7.9 + (–5.5)

By commutative property of addition,

a + b = b + a

This, is commutative property of addition

Option C

–17.5 + 0 = –17.5

This is also not a example of associative property

Option D

(8.4 + 10.3) + (–4.1) = 8.4 + (10.3 + (–4.1))

We can group the numbers in any combination

This is a example of associative property of addition
