There were 42 runners to start a race. In the first half of the race, 1 over 3 of them dropped out. In the second half of the race, 4 over 7 of the remaining runners dropped out. How many runners finished the race?
1/3 of 42 is 14 (42 divided by 3 is 14) so u subtract 14 from 42 which is 28. Then you would divide 28 by 7 which is 4 and then since the fraction is 4/7, u would multiply 4 and 4 to get 16. and finally subtract 28 and 16.
