Official Solution:
\(\frac{1}{\sqrt{51}}\) is between:
A. 0 and \(\frac{1}{9}\)
B. \(\frac{1}{9}\) and \(\frac{1}{7}\)
C. \(\frac{1}{7}\) and \(\frac{1}{6}\)
D. \(\frac{1}{6}\) and \(\frac{1}{5}\)
E. \(\frac{1}{5}\) and \(\frac{1}{2}\)
Since \((\sqrt{49} = 7) \lt \sqrt{51} \lt (\sqrt{81} = 9)\), it follows that \(\frac{1}{\sqrt{51}}\) is between \(\frac{1}{9}\) and \(\frac{1}{7}\).
Answer: B

I might be being stupid here but is it not also between 0 and 1/9?
