In the Central City Grand Prix, out of 30 cars that started the race, 12 of them finished. What percent of the cars finished the race? What percent did not finish the race?

Question

i really need someone to answer this for me, i'm not that smart

Answer 1

12/30 finished

12/30 = 2/5 = 0.40 = 40%

the percent that didn't finish is 100%-40% = 60%

18/30 = 3/5 = 6/10 = 0.60 = 60%
