90% completed it.

30% are men.

Let the total men be x.

30x/100=270

=x=270*100/30

=x=900

So there were 900 men who started the marathon.

Hope it helps.

Total percentage of runners that complete the marathon

= 90%


Total percentage of male runners that complete the marathon

= 30% of 90%

= 0.3 x 90

= 27%


Total percentage of male runners that complete the marathons= 27%

Total male runners that complete the marathons= 270

27% = 270

1% = 270 ÷ 27 = 10


1% = 10 runners

100% = 10 x 100 = 1000 runners


Answer: There are 1000 runners in the marathon.
