Answers
Answer:
None of these
Step-by-step explanation:
OPTION A- A set is closed under an operation if performance of that operation on members of the set always produces a member of that set. For example, the positive integers are closed under addition, but not under subtraction: is not a positive integer even though both 1 and 2 are positive integers.
OPTION B- Division of the whole numbers is not commutative. If a and b are the two whole numbers, then a ÷ b ≠ b ÷ a.
OPTION C- The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis.
So the correct answer is none of these, option D.
Answer:
option B is the correct answer
