conversations.value: Can you guide me through solving this problem: Willie came back from Europe with 70 euros. Normally 5 euros is worth 1 dollar, but the money exchange at the airport will only give Willie 5/7ths of the official exchange rate. How many dollars does Willie get?
conversations.from: assistant
conversations.value: First first out how many euros Willie should have gotten using the official exchange rate: 70 euros / 5 euros/dollar = $14
  Then multiply this quantity by 5/7 to find how many dollars he actually got: 14 dollars * 5/7 = $2 * 5= $10
