To determine which of the provided numbers is a rational number between 5 and 5, we first need to clarify that there is no number between 5 and 5, as they are the same. Therefore, it appears that there might be a misunderstanding in the question.
However, we can identify which of the options provided are rational numbers, but since none can be between two identical values (5 and 5), we conclude that there are no rational numbers fitting that description.
The numbers given are:
- \(1\) (rational)
- \(4\) (rational)
- \(\sqrt{26}\) (irrational)
- \(5\) (rational)
- \(1/8\) (rational)
- \(5/2\) (rational)
- \(5.5\) (rational)
- \(1/3\) (rational)
So while all except \(\sqrt{26}\) are rational, none of them can be between 5 and 5. Please clarify if the range is meant to be something other than the same endpoint.
