Which answer describes the type of numbers that are dense?
whole numbers and integers
whole numbers but not integers
rational numbers and irrational numbers
rational numbers but not irrational numbers

Rational numbers and irrational numbers

Step-by-step explanation:

A subset A of a topological space X is called dense (in X) if every point x in X either belongs to A or is a limit point of A, in other words

Informally, for every point in X, the point is either in A or is "close" to a member of A.

The rational numbers are a dense subset of the real numbers because every real number either is a rational number or has a rational number arbitrarily close to it. This set of numbers is countable dense set.

The irrational numbers are a dense subset of the real numbers because every real number either is an irrational number or has an irrational number arbitrarily close to it. This set of numbers is uncountable dense set.
