It seems like you're presenting a fraction, \( \frac{3}{18} \). This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3:
\[ \frac{3 \div 3}{18 \div 3} = \frac{1}{6} \]
So, \( \frac{3}{18} \) simplifies to \( \frac{1}{6} \). If you meant something else, please provide more details!
