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.

To find the descending numeric order of the laps completed, we need to convert all the fractions and decimals to a common denominator.

First, we can convert the fractions to a common denominator of 40:
Sara completed (4/5) * 40 = 32 laps.
Jamie completed (5/8) * 40 = 25 laps.
Keenan completed (5/9) * 40 = 22.222 (rounded to 22) laps.

Now, let's convert the decimals to a common denominator of 40 as well:
Maya completed 0.833 * 40 = 33.32 (rounded to 33) laps.
Trey completed 0.875 * 40 = 35 laps.

In descending order, the laps completed are: Trey, Maya, Sara, Jamie, Keenan.
Descending numeric order: 35, 33, 32, 25, 22.
