Which answer describes the type of numbers that are dense?

A set of numbers is dense if there is always another number from the set between any two distinct numbers. Both rational numbers and irrational numbers have this property: between any two distinct real numbers, you can find a rational number and also an irrational number. Whole numbers and integers are not dense, since there can be no whole number or integer between consecutive ones. Therefore, the correct choice is “rational numbers and irrational numbers.”
