Question

Which expression illustrates the associative property of addition?
(3 + 19) – 12 = (3 + 12) – 19
O 3 + (19 – 12) = 3 + (19 + 12)
(3 + 19) – 12 = 3 + (19 – 12)
o 3+ (19 – 12) = 3 – (19 + 12)

Step-by-step explanation: on edge

### (3 + 19) – 12 = 3 + (19 – 12) represent associative property of addition

Solution:

The associative property of addition of three numbers a, b and c is given as: Option A

( 3 + 19 ) – 12 = (3 + 12) – 19

Here, +19 in left side of equation is written as -19 in right side of equation

Therefore, it does not represent associative property of addition

Option B

3 + (19 – 12) = 3 + (19 + 12)

Here, -12 in left side of equation is written as +12 in right side of equation

Therefore, it does not represent associative property of addition

Option C

(3 + 19) – 12 = 3 + (19 – 12)

22 – 12 = 3 + 7

10 = 10

This represents associative property of addition

Option D

3 + (19 – 12) = 3 – (19 + 12)

3 + 7 =  3 – 7

10 not equal to -4

Therefore, it does not represent associative property of addition
