No.
Yes. They are closed under addition, subtraction, multiplication. The rational numbers WITHOUT ZERO are closed under division.
No. Zero is a rational number, but division by zero is not defined.
No. Integers are not closed under division because they consist of negative and positive whole numbers. NO FRACTIONS!No.For a set to be closed under an operation, the result of the operation on any members of the set must be a member of the set.When the integer one (1) is divided by the integer four (4) the result is not an integer (1/4 = 0.25) and so not member of the set; thus integers are not closed under division.
The set of whole numbers is not closed under division (by non-zero whole numbers).
Rational numbers are closed under addition, subtraction, multiplication. They are not closed under division, since you can't divide by zero. However, rational numbers excluding the zero are closed under division.
They are closed under all except that division by zero is not defined.
No, they are not.
No.
no
no
No, the natural numbers are not closed under division. For example, 2 and 3 are natural numbers, but 2/3 is not.
yes
No.
The whole numbers are not closed under division! The statement is false since, for example, 2/3 is not a whole number.
No, it is not. Division by zero (a rational) is not defined.
Integers are closed under division I think o.o. It's either counting numbers, integers or whole numbers . I cant remember :/
