To find a rational number between 5 and 514, we can evaluate the options given:
- 517 - This is greater than 514.
- 5 (1/7) - This can be written as \(5 + \frac{1}{7} = 5.142857...\), which is between 5 and 514.
- 513 - This is greater than 514.
- 5 (1/3) - This can be written as \(5 + \frac{1}{3} = 5.3333...\), which is also between 5 and 514.
- 525 - This is greater than 514.
- \( \sqrt{26} \) - This is approximately \(5.099\), which is also between 5 and 514.
All of the following are rational numbers between 5 and 514:
- \(5 \frac{1}{7}\)
- \(5 \frac{1}{3}\)
- \( \sqrt{26} \)
However, since you only need to identify one such number, the option 5 (1/7) is a suitable choice.
