Asha wanted to count the numbers between \(-9\) and \(12\) . She found that totally \(20\) integers are present, with \(8\) negative integers, \(zero\) and \(11\) positive integers present between \(-9\) and \(12\) (excluding \(-9\) and \(12\)). She also gets to know that there are no integers present between any two consecutive integers, that is, for example, between \(8\) and \(9\) there is no integer. So, between any two consecutive integers the number of integers is \(0\).
She doubts whether the same will happen in case of rational numbers too?
She took two rational numbers
She converted them to rational numbers with same denominators, for which the denominator of both the numbers should be converted into LCM.
She found the LCM of (\(2\),\(3\)) \(= 6\).
Converting both the numbers with denominator as \(6\),
We have,
(or)
She could find rational numbers between .
She doubts are there only \(4\) rational numbers between . She gets to know there are
more than \(4\) rational numbers between because if we find the multiples of denominators, then many more rational numbers can be inserted between .
For example,
Now, between there are \(9\) rational numbers present.
