Solution:
Given that we have to find the associative property of addition
[tex]a + (b+c) =(a+b) + c[/tex]
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
