Which is an example of the associative property? –(18.9 + 3.2) = –18.9 + (–3.2)

Question

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))

    (8.4 + 10.3) + (–4.1) = 8.4 + (10.3 + (–4.1)) is a example of  associative property of addition

    Solution:

    Given that we have to find the associative property of addition

    a + (b+c) =(a+b) + c

    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
