To compare the lengths of the trails, we first convert each of them to improper fractions or decimals for easier comparison.
- Trail A: \( 6 \frac{8}{15} = \frac{6 \times 15 + 8}{15} = \frac{90 + 8}{15} = \frac{98}{15} \approx 6.53 \)
- Trail B: \( 6 \frac{1}{5} = \frac{6 \times 5 + 1}{5} = \frac{30 + 1}{5} = \frac{31}{5} = 6.2 \)
- 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:
- Trail C: \( 6 \frac{2}{3} \)
- Trail A: \( 6 \frac{8}{15} \)
- Trail B: \( 6 \frac{1}{5} \)
Thus, the correct order from longest to shortest is C, A, B.
Answer: C, A, B
