As many as you like providing that they can be expressed as fractions.
There are infinitely many rational numbers between any two rational numbers. And the cardinality of irrational numbers between any two rational numbers is even greater.
There are infinitely many rational numbers between any two consecutive rational numbers. This is because rational numbers can be expressed as fractions, and between any two fractions, an infinite number of other fractions can be found by taking the average of the two given fractions. Therefore, the set of rational numbers is dense, meaning there is no smallest gap between any two rational numbers.
There is an infinite number of them between any two rational numbers.
Yes, there are infinitely many of them!
There are countably infinite rational numbers between any two numbers.
Yes. There are infinitely many rational numbers between any two real numbers.
No. There are infinitely many rational numbers between any two integers.
Infinitely many. Between any two different real numbers (not necessarily rational) there are infinitely many rational numbers, and infinitely many irrational numbers.
There are infinitely many rational numbers between any two rational numbers - no matter how close together they are.
Rational numbers are infinitely dense and that means that there are infiitely many rational numbers between any two numbers.
Find the arithmetic average of the two rational numbers. It will be a rational number and will be between the two numbers.
Infinitely many. The set of rational numbers (as well as irrationals) are infinitely dense. This means that no matter how close you pick two rational numbers, there are infinitely many rational numbers between them. And if you pick any two of those, there are infinitely many between those two.
