Out of 270 racers who started the marathon, 247 completed the race, 14 gave up, and 9 were disqualified. What percentage did not complete the marathon?

8.5%

Step-by-step explanation:

Total number of racers = 270

From the question, we have two categories who did not complete the race.

a. 14 that gave up

b. 9 that were disqualified

Total number of those who didn't complete race = 14 +9 = 23

To get the percentage of this group in the marathon:

= 0.0851 *100

= 8.5percent
