The answer to your question is A. rational numbers. Rational numbers are closed under any set of operations. Integers are not closed under division because 1/2 is not an integer. The set {-1, 0, 1} is also not closed under division because -1/5 does not fall in that set. Whole numbers are not closed under division because 5/3 will produce a number that is not a whole integer. Your answer is A. rational numbers.

A. Rational numbers are closed under division. If you divide a rational number, it will remain a rational number. If you divide an integer or a whole number, there is a chance that the new resulting number will not be an integer or a whole number.
