commutative property of multiplication
Step-by-step explanation:
The commutative property of multiplication is correct. The commutative property of multiplication is basically arranging the numbers in any way and it won't change the product.
The associative property of multiplication is arranging the numbers in parenthesis and it won't change the product either.
The answer is 25%.
First: work out the difference between the two numbers you are comparing.

7÷
28=.25
.25*100=25
