To find a rational number between 5 and \(5 \frac{1}{4}\), we first need to convert \(5 \frac{1}{4}\) into an improper fraction.
The improper fraction is \( \frac{21}{4} \) (since \(5 \times 4 + 1 = 21\)).
Now, we need to identify which of the given options is a rational number between \(5\) (or \( \frac{20}{4} \)) and \(5 \frac{1}{4}\) (or \( \frac{21}{4} \)).
Let's evaluate each response:
- \( \sqrt{26} \): This is an irrational number.
- \( \frac{51}{8} \): This can be evaluated as \(6.375\). This is greater than \(5 \frac{1}{4} (5.25)\).
- \( \frac{52}{5} \): This evaluates to \(10.4\), which is also greater than \(5 \frac{1}{4}\).
- \( \frac{51}{3} \): This evaluates to \(17\), which is also greater than \(5 \frac{1}{4}\).
None of these options seem to fall between \(5\) and \(5 \frac{1}{4}\). However, \( \frac{51}{8} \) is the closest to falling in this range and is rational. But we see that it’s too high.
If you have the possibility to find a more exact rational number or an option of choices, \(5 \frac{1}{8} (5.125)\) would be a candidate that lies between \(5\) and \(5 \frac{1}{4}\).
Please double-check the options, and if they allow for a narrower choice, \( \frac{21}{8} (2.625)\) or any form of \( \frac{21}{8}\) could yield the answer.
If you can clarify or provide more options, I would be glad to assist further!
