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.(2 points)

From the given information, we can convert each fraction into a decimal representation:

- Sara completed 4/5 of the laps = 4/5 = 0.8
- Jamie completed 5/8 of the laps = 5/8 = 0.625
- Keenan completed 5/9 of the laps = 5/9 ≈ 0.5556
- Maya completed 0.833 (already in decimal form)
- Trey completed 0.875

Now let's arrange them in descending order:

0.875 > 0.833 > 0.8 > 0.625 > 0.5556

So, the descending order of laps completed is:

Trey, Maya, Sara, Jamie, Keenan.
