conversations.value: Please show me the solution for: There are 80 men in a race. 1/4 of the men tripped and were unable to finish. 2/3 of the remaining men were dehydrated and 1/5 of those dehydrated men couldn't finish the race. How many men finished the race?

conversations.value: 1/4 of 80 men is 80/4=20 men
  20 men couldn't finish, so 80-20=60 men remain
  60*2/3 = 40 men were dehydrated
  1/5 of the dehydrated couldn't finish 40*1/5=8 men
  60-8=52 men finished the race
