Yes, \( 2 \frac{1}{6} \) (which is the mixed number representing 2 and one-sixth) is a rational number. 

A rational number is any number that can be expressed as the quotient or fraction \(\frac{a}{b}\), where \(a\) and \(b\) are integers, and \(b\) is not zero. 

To express \( 2 \frac{1}{6} \) as an improper fraction:

\[
2 \frac{1}{6} = \frac{2 \times 6 + 1}{6} = \frac{12 + 1}{6} = \frac{13}{6}
\]

Since \( \frac{13}{6} \) is a fraction with both the numerator and the denominator as integers, \( 2 \frac{1}{6} \) is indeed a rational number.
