Which of the following shows the Commutative Property of Multiplication?(1 point)
Responses
a×b=b×a
a times b equals b times a
a×(−1)=−a
a times left parenthesis negative 1 right parenthesis equals negative a
a×1=a
a times 1 equals a
a×(b×c)=(a×b)×c
a times left parenthesis b times c right parenthesis equals left parenthesis a times b right parenthesis times c
Responses
a×b=b×a
a times b equals b times a
a×(−1)=−a
a times left parenthesis negative 1 right parenthesis equals negative a
a×1=a
a times 1 equals a
a×(b×c)=(a×b)×c
a times left parenthesis b times c right parenthesis equals left parenthesis a times b right parenthesis times c
The correct answer is: a×b=b×a . This equation demonstrates the Commutative Property of Multiplication, which states that the order of the factors does not change the product.
