Example Questions

Example Question #1 : Understanding The Associative Property

Which is an example of associative property? 

Possible Answers:

\(\displaystyle 5+2=3\) and \(\displaystyle 2+5=3\)

\(\displaystyle 6+4+3=13\) and \(\displaystyle 10+3=13\)

     

\(\displaystyle 6+4+3=13\) and \(\displaystyle 8+6=13\)

\(\displaystyle 3+2=5\) and \(\displaystyle 2+3=5\)

Correct answer:

\(\displaystyle 6+4+3=13\) and \(\displaystyle 10+3=13\)

     

Explanation:

The associative property says that you can group a set of numbers in a series, and still get the same answer. If we group \(\displaystyle 6+4\) to get \(\displaystyle 10\), and then add \(\displaystyle 10+3\) we get a sum of \(\displaystyle 13\)

Example Question #2 : Understanding The Associative Property

Which is an example of associative property?

Possible Answers:

\(\displaystyle 10+3=7\) and \(\displaystyle 3+10=7\)

\(\displaystyle 7+3+3=13\) and \(\displaystyle 7+9=13\)

\(\displaystyle 7+3+3=13\) and \(\displaystyle 10+3=13\)

     

\(\displaystyle 7+3=10\) and \(\displaystyle 3+7=10\)

Correct answer:

\(\displaystyle 7+3+3=13\) and \(\displaystyle 10+3=13\)

     

Explanation:

The associative property says that you can group a set of numbers in a series, and still get the same answer. If we group \(\displaystyle 7+3\) to get \(\displaystyle 10\), and then add \(\displaystyle 10+3\) we get a sum of \(\displaystyle 13\)

Example Question #1 : Understanding The Associative Property

Which is an example of associative property?

Possible Answers:

\(\displaystyle 14+6=8\) and \(\displaystyle 6+14=8\)

\(\displaystyle 6+8+4=18\) and \(\displaystyle 14+6=18\)

\(\displaystyle 6+8+4=18\) and \(\displaystyle 10+8=18\)

 

\(\displaystyle 6+8=14\) and \(\displaystyle 8+6=14\)

Correct answer:

\(\displaystyle 6+8+4=18\) and \(\displaystyle 10+8=18\)

 

Explanation:

The associative property says that you can group a set of numbers in a series, and still get the same answer. If we group \(\displaystyle 6+4\)to get \(\displaystyle 10\), and then add \(\displaystyle 10+8\) we get a sum of \(\displaystyle 18\)

Example Question #2 : Understanding The Associative Property

Which is an example of associative property?

Possible Answers:

\(\displaystyle 4+9+1=14\) and \(\displaystyle 6+9=14\)

\(\displaystyle 4+9+1=14\) and \(\displaystyle 10+4=14\)

 

\(\displaystyle 13+4=9\) and \(\displaystyle 4+13=9\)

\(\displaystyle 4+9=1\) and \(\displaystyle 9+4=13\)

Correct answer:

\(\displaystyle 4+9+1=14\) and \(\displaystyle 10+4=14\)

 

Explanation:

The associative property says that you can group a set of numbers in a series, and still get the same answer. If we group \(\displaystyle 9+1\) to get \(\displaystyle 10\), and then add \(\displaystyle 10+4\)we get a sum of \(\displaystyle 14\)

Example Question #5 : Understanding The Associative Property

Which is an example of associative property?

Possible Answers:

\(\displaystyle 16+7=9\) and \(\displaystyle 7+16=9\)

\(\displaystyle 9+7+3=19\) and \(\displaystyle 17+3=19\)

\(\displaystyle 9+7=16\) and \(\displaystyle 7+9=16\)

\(\displaystyle 9+7+3=19\) and \(\displaystyle 9+10=19\)

  

Correct answer:

\(\displaystyle 9+7+3=19\) and \(\displaystyle 9+10=19\)

  

Explanation:

The associative property says that you can group a set of numbers in a series, and still get the same answer. If we group \(\displaystyle 7+3\) to get \(\displaystyle 10\), and then add \(\displaystyle 10+9\) we get a sum of \(\displaystyle 19\)

Example Question #6 : Understanding The Associative Property

Which is an example of the associative property?

Possible Answers:

\(\displaystyle 6+(3+2)=11\) and \(\displaystyle (6+3) + 2 = 11\)

\(\displaystyle 6+3+2=11\) and \(\displaystyle 6+6=11\)

\(\displaystyle 6+5=11\) and \(\displaystyle 6=11-5\)

\(\displaystyle 6+3=9\) and \(\displaystyle 3+6=9\)

Correct answer:

\(\displaystyle 6+(3+2)=11\) and \(\displaystyle (6+3) + 2 = 11\)

Explanation:

The associative property says that, when you are only adding or only multiplying, the way you group the items in a series does not matter.  Given 6 + 3 + 2 = 11, whether you group (6 + 3) + 2 or 6 + (3 + 2), the outcome does not change as the order in which you sum the numbers does not matter.
