conversations.value: I would love to understand how to solve this problem: During the hot dog eating contest, the 1st competitor ate 12 hot dogs in 3 minutes.  The 2nd competitor ate twice that amount and the 3rd competitor ate 25% less than the 2nd competitor.  How many hotdogs did the 3rd competitor eat?
  Can you explain?

conversations.value: The 2nd competitor ate twice the amount of the 1st competitor's 12 hot dogs So he ate 2*12 = 24 hot dogs
  The 3rd competitor ate 25% less than the 2nd's 24 hot dogs, which is 24/4 = 6 hot dogs
  If the 2nd competitor ate 24 hot dogs, and the 3rd ate 25% less than that, then the 3rd competitor ate 24 - 6 = 18 hot dogs
