Question

Which of the following best illustrates the associative property of addition $?$

• A. $6+(4+9)=(6+4)+9$
• B. $6+(4+9)=(7+3)+9$
• C. $3+(9+6)=(2+10)+6$
• D. All of the above.

Answer 1

The correct option is A $6+(4+9)=(6+4)+9$

The associative property states that when three or more numbers are added, the sum is the same regardless of the grouping of the addends.

For eg :

3+(2+1) = (3+2)+1

3+3 = 5+1

6 = 6

L.H.S = R.H.S

Therefore, $6+(4+9)=(6+4)+9$ best illustrates the associative property of addition.
