Express the ratio as a fraction

We need to find the fraction of students in the class who are men.
The total number of students is \(27\).
The number of men is \(9\).
The fraction representing the men is:
\[
\frac{9}{27}
\]

Simplify the fraction

Using the Fraction Simplification knowledge point
\[
\frac{9}{27} = \frac{9 \div 9}{27 \div 9} = \frac{1}{3}
\]
