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 = 201/100
2.001 = 2001/1000
... 2.4 = 24/10 and so on.
So there are infinitely many rational numbers b/w 2 and 3.
There are infinitely many rational numbers between any two numbers. Examples of rational numbers between 2 and 2.5 are: 2.1, 2.2, 2.3
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.
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.

2/3 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
There are infinitely many rational numbers between any two (different) numbers, no matter how close together they are.
There are infinitely many rational numbers between any two numbers. Examples of rational numbers between 2 and 2.5 are: 2.1, 2.2, 2.3
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.
No, there are more irrational numbers between 1 and 2 than there are rational numbers.
There are infinitely many rational numbers between 2 and 27.
No, not at all. There are more irrational numbers between 1 and 2 than there are rational numbers in total!
Add them together and divide by 2 will give one of the rational numbers between two given rational numbers.
There are countably infinite (Aleph-Null) of such numbers.
All rational numbers are fractional but all fractional numbers are not rational. For example, pi/2 is fractional but not rational.
Infinitely many. In fact, there are more irrational numbers between 1 and 2 as there are rational numbers - in total. The cardinality of this set is Aleph-0ne.

Exploration task: Inserting rational numbers between two given rational numbers 1. Take any two rational numbers. 2. Add them. 3. Divide the result obtained by 2. 4. Observe the number obtained. Is the answer a rational number? Is it between two given numbers? Brainstorming: How many rational numbers can be inserted between two rational numbers?
