No, only for Irrational Numbers.
Actually, that's not true.
Take any two rationals, a/b and c/d where a,b,c,d are integers and b,d are nonzero.
The average of a/b and c/d is (ad+bc)/2bd. This is a rational number between a/b and c/d.
Now take the average of this new number and the first number. This gives you:
(2abd+abd+cb^2)/(2db^2)
which is rational and also between the first and third number.
We could carry on this process ad infinitum. We would then have an infinite collection of numbers between a/b and c/d.
Hence the answer is yes.
That is the property of infinite density of rational numbers. If x and y are any two rational numbers then w = (x + y)/2 is a rational number between them. And then there is a rational number between x and w. This process can be continued without end.
There are an infinite number of rational numbers between any two rational numbers. And 2 and 7 are rational numbers. Here's an example. Take 2 and 7 and find the number halfway between them: (2 + 7)/2 = 9/2, which is rational. Then you can take 9/2 and 2 and find a rational number halfway: 2 + 9/2 = 13/2, then divide by 2 = 13/4. No matter how close the rational numbers become, you can add them together and divide by 2, and the new number will be rational, and be in between the other 2.
There are infinitely many rational numbers and irrational numbers but the cardinality of irrationals is larger by an order of magnitude.If the cardinality of the countably infinite rational numbers is represented by a, then the cardinality of irrationals is 2^a.
No, there are more irrational numbers between 1 and 2 than there are rational numbers.
No, not at all. There are more irrational numbers between 1 and 2 than there are rational numbers in total!

There are countably infinite (Aleph-Null) of such numbers.
There are not THE five rational numbers between -2 and -1, there are an infinite number of them. -1.1, -1.01, -1.001, -1.000001 and -1.456798435854 are five possibilities.

we pretty much just assume we can count to the number 2
A rational number is any number that, when put into decimal form, terminates after a finite amount of digits OR begins to repeat the same pattern of digits. An easy way to find rational numbers is that any number that can be expressed in a fraction (1/2, 9/4, etc) of two integers.There is an infinite number of rational numbers between any two rational numbers. For example, say we have the numbers 1 and 2. What if you add them and divide by 2? Is that a rational number? Is it between 1 and 2? And to see that there is an infinite number of numbers between 1 and 2, take the number you just found, it is 3/2, now find a number between it and 2. You can keep doing this.

There are infinite rational numbers between 2 and 3.Explanation:Let us write a few decimal numbers between 2 and 3: 2.01, 2.001, 2.0001,.., 2.4, 2.90 etc. Just change digits after the decimal point and this way we can write infinite decimal numbers between 2 and 3. And each decimal number can be expressed in the form of p/q(rational number)2.01 = 201/1002.001 = 2001/1000... 2.4 = 24/10 and so on.So there are infinitely many rational numbers b/w 2 and 3.

No, there are more irrational numbers between 1 and 2 than there are rational numbers.
No, not at all. There are more irrational numbers between 1 and 2 than there are rational numbers in total!
A rational number is a number that can be expressed as the ratio between two integers, so 5 and 6 and both rational themselves (5/1 and 6/1 respectively). As there is an infinite number of integers, there are an infinite number of rational numbers between 5 and 6, but an example is 5.5 (11/2).No, the number between 5 and 6 is Derf.haha
