To determine the order of the trails from shortest to longest, we need to convert each mixed number to an improper fraction for easier comparison.

  1. Trail A: \( 5 \frac{9}{10} = \frac{5 \times 10 + 9}{10} = \frac{50 + 9}{10} = \frac{59}{10} \).

  2. Trail B: \( 5 \frac{1}{7} = \frac{5 \times 7 + 1}{7} = \frac{35 + 1}{7} = \frac{36}{7} \).

  3. Trail C: \( 5 \frac{5}{9} = \frac{5 \times 9 + 5}{9} = \frac{45 + 5}{9} = \frac{50}{9} \).

Now we will convert these fractions to a common denominator to compare them more easily. The least common multiple of 10, 7, and 9 is 630.

Convert Trail A: \[ \frac{59}{10} = \frac{59 \times 63}{10 \times 63} = \frac{3717}{630} \]

Convert Trail B: \[ \frac{36}{7} = \frac{36 \times 90}{7 \times 90} = \frac{3240}{630} \]

Convert Trail C: \[ \frac{50}{9} = \frac{50 \times 70}{9 \times 70} = \frac{3500}{630} \]

Now we can compare:

  • Trail A: \( \frac{3717}{630} \)
  • Trail B: \( \frac{3240}{630} \)
  • Trail C: \( \frac{3500}{630} \)

Now we arrange these from smallest to largest:

  • B: \( \frac{3240}{630} \) (5 1/7)
  • C: \( \frac{3500}{630} \) (5 5/9)
  • A: \( \frac{3717}{630} \) (5 9/10)

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