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 put the laps completed in descending numeric order, we need to convert all the fractions and decimals to a common format.

Sara completed 4/5 of the 20 laps, which is (4/5) * 20 = 16 laps.
Jamie completed 5/8 of the 20 laps, which is (5/8) * 20 = 12.5 laps.
Keenan completed 5/9 of the 20 laps, which is (5/9) * 20 = 11.11 laps.
Maya completed 0.833 of the 20 laps, which is 0.833 * 20 = 16.66 laps.
Trey completed 0.875 of the 20 laps, which is 0.875 * 20 = 17.5 laps.

Now we can order the laps completed from greatest to least:

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