To arrange the fractions \( \frac{3}{6} \), \( \frac{1}{6} \), \( \frac{5}{6} \), and \( \frac{2}{6} \) from smallest to largest, we can compare the numerators since they all have a common denominator of 6.
Here are the fractions with their equivalent values:
- \( \frac{1}{6} = 1 \)
- \( \frac{2}{6} = 2 \)
- \( \frac{3}{6} = 3 \)
- \( \frac{5}{6} = 5 \)
Now, we can list them in ascending order based on their numerators:
- \( \frac{1}{6} \)
- \( \frac{2}{6} \)
- \( \frac{3}{6} \)
- \( \frac{5}{6} \)
Thus, the order from smallest to largest is:
\(\frac{1}{6}, \frac{2}{6}, \frac{3}{6}, \frac{5}{6}\).
