A track team needed to run or jog 20 laps for their practice. 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.

To find the descending numeric order of the laps completed, we need to convert all fractions into decimals.

Sara completed 4/5 of the laps: 4/5 = 0.8 laps
Jamie completed 5/8 of the laps: 5/8 = 0.625 laps
Keenan completed 5/9 of the laps: 5/9 = 0.5556 laps
Maya completed 0.833 laps
Trey completed 0.875 laps

Now, arranging the laps in descending order:
0.875 laps (Trey)
0.833 laps (Maya)
0.8 laps (Sara)
0.625 laps (Jamie)
0.5556 laps (Keenan)

The descending numeric order of the laps completed is: 0.875, 0.833, 0.8, 0.625, 0.5556.
