A track team needed to run or jog 20 laps for their practice. Of the total 20 laps, Sara completed 4/5

To identify the descending numeric order of the laps completed by each member of the track team, we need to convert all the fractions and decimals into the same format (decimal).

1. Sara: Completed \( \frac{4}{5} \) laps.

   • \( \frac{4}{5} = 0.8 \)

2. Jamie: Completed \( \frac{5}{8} \) laps.

   • \( \frac{5}{8} = 0.625 \)

3. Keenan: Completed \( \frac{5}{9} \) laps.

   • \( \frac{5}{9} \approx 0.555 \)

4. Maya: Completed \( 0.833 \) laps.

5. Trey: Completed \( 0.875 \) laps.

Now, we list all the completed laps in decimal form:

• Sara: 0.8
• Jamie: 0.625
• Keenan: approximately 0.555
• Maya: 0.833
• Trey: 0.875

Next, we will arrange them in descending order:

1. Trey: 0.875
2. Maya: 0.833
3. Sara: 0.8
4. Jamie: 0.625
5. Keenan: 0.555

Therefore, the descending numeric order of the laps completed is:

Trey, Maya, Sara, Jamie, Keenan

You can enter this in the provided blanks as: Trey, Maya, Sara, Jamie, Keenan
