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

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)

    Option C

    (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:

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

    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
