A track team needed to run or jog 20 laps for their practice. Of the total 20 laps, Sara completed 4/5 , Jamie completed 5/8 , Keenan completed 5/9, Maya completed 0.833, and Trey completed 0.875. Identify the descending numeric order of the laps completed.

Answer 1

To compare the laps completed by each team member, we first need to convert all the fractions and decimals into a common form. Since the total number of laps is 20, we can convert everything into laps for easier comparison.

1. Sara:

   • Laps completed: \( \frac{4}{5} \times 20 = 16 \) laps

2. Jamie:

   • Laps completed: \( \frac{5}{8} \times 20 = 12.5 \) laps

3. Keenan:

   • Laps completed: \( \frac{5}{9} \times 20 \approx 11.11 \) laps

4. Maya:

   • Laps completed: \( 0.833 \times 20 \approx 16.66 \) laps

5. Trey:

   • Laps completed: \( 0.875 \times 20 = 17.5 \) laps

Now let's list the laps completed by each member:

• Sara: 16 laps
• Jamie: 12.5 laps
• Keenan: ~11.11 laps
• Maya: ~16.66 laps
• Trey: 17.5 laps

Now, we put these values in descending order:

1. Trey: 17.5 laps
2. Maya: ~16.66 laps
3. Sara: 16 laps
4. Jamie: 12.5 laps
5. Keenan: ~11.11 laps

So the descending numeric order of the laps completed is:

1. Trey (17.5 laps)
2. Maya (16.66 laps)
3. Sara (16 laps)
4. Jamie (12.5 laps)
5. Keenan (11.11 laps)
