Question

There were 72 runners to start a race. in the first half of the race, 13 of them dropped out. in the second half of the race, 23 of the remaining runners dropped out. how many runners finished the race?

Answer 1

All you would need to to is do 13+23= 33 to get the total amount of people who dropped out, then do 72 ( the number in the beginning and subtract 33 from it because those are the people who dropped out so 72-33=39. 39 people finished the race.
