Example Questions

Example Question #11 : Understanding Properties Of Multiplication And The Relationship Between Multiplication And Division

Using the commutative property, if \(\displaystyle 11\times4=44\) what else is known?

Possible Answers:

\(\displaystyle 1\times44=44\)

\(\displaystyle 4\times11=44\)

\(\displaystyle 22\times2=44\)

\(\displaystyle 44\times1=44\)

\(\displaystyle 2\times22=44\)

Correct answer:

\(\displaystyle 4\times11=44\)

Explanation:

The commutative property of multiplication says that we can multiply numbers in any order and our product, or answer, will be the same. 

Though all of our answer choices do equal \(\displaystyle 44\), we started with \(\displaystyle 11\times4\) so our answer must use those numbers, but in a different order. 

\(\displaystyle 11\times4=44\) and \(\displaystyle 4\times11=44\) demonstrates the commutative property of multiplication. 

Example Question #12 : Understanding Properties Of Multiplication And The Relationship Between Multiplication And Division

Using the commutative property, if \(\displaystyle 12\times5=60\) what else is known?

 

Possible Answers:

\(\displaystyle 6\times10=60\)

\(\displaystyle 20\times3=60\)

\(\displaystyle 15\times4=60\)

\(\displaystyle 5\times12=60\)

 

\(\displaystyle 2\times30=60\)

Correct answer:

\(\displaystyle 5\times12=60\)

 

Explanation:

The commutative property of multiplication says that we can multiply numbers in any order and our product, or answer, will be the same. 

Though all of our answer choices do equal \(\displaystyle 60\), we started with \(\displaystyle 12\times5\) so our answer must use those numbers, but in a different order. 

\(\displaystyle 12\times5=60\) and \(\displaystyle 5\times12=60\) demonstrates the commutative property of multiplication.
