There's an infinite list of rational numbers that are all between 2.1 and 3.9 .
Here are a few of them:
2.11
2.12
2.2
2.3
2.4
2.6
2.7
2.9
2.99
2.99999999999
3.0

.
etc.
Any number that you can completely write down on paper is rational.
An irrational number cannot be rational, so choosing at random is an irrelevance.
There are [countably] infinite rational number between any two rational numbers. There is, therefore, no maximum.
There cannot be any rational"between" the same number.
It is: 119.5 which is a rational number
7.8 is a rational number
.95 is a rational number or square root of 121 a rational number
Yes, 3.4 is a rational number between 3 and 4: 3.4 is between 3 and 4, and 3.4 = 34/10 = 17/5 which is a rational number. The rational number midway between 3 and 4 is 3.5
Most numbers ARE rational. For instance all the integers and most real numbers are rational numbers. To be an irrational number a real number must be impossible to express as a ratio of integers.
There are an infinite number of rational numbers between any two rational numbers.
It is 1
The average of the two will be rational and it will be between them.
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.
