To compare the lengths of the trails, we first convert each of them to improper fractions or decimals for easier comparison.

  1. Trail A: \( 6 \frac{8}{15} = \frac{6 \times 15 + 8}{15} = \frac{90 + 8}{15} = \frac{98}{15} \approx 6.53 \)
  2. Trail B: \( 6 \frac{1}{5} = \frac{6 \times 5 + 1}{5} = \frac{30 + 1}{5} = \frac{31}{5} = 6.2 \)
  3. Trail C: \( 6 \frac{2}{3} = \frac{6 \times 3 + 2}{3} = \frac{18 + 2}{3} = \frac{20}{3} \approx 6.67 \)

Now let's compare the approximate values:

  • Trail A: \( \approx 6.53 \)
  • Trail B: \( 6.2 \)
  • Trail C: \( \approx 6.67 \)

Ordering them from longest to shortest:

  1. Trail C: \( 6 \frac{2}{3} \)
  2. Trail A: \( 6 \frac{8}{15} \)
  3. Trail B: \( 6 \frac{1}{5} \)

Thus, the correct order from longest to shortest is C, A, B.

Answer: C, A, B
