conversations.value: I'm stuck on this math problem: Bob grew corn in his garden and is ready to harvest it. He has 5 rows of corn, and each row has 80 corn stalks. About every 8 corn stalks will produce a bushel of corn. How many bushels of corn will Bob harvest?
  Can you help?

conversations.value: Bob has 5 rows of corn, each with 80 corn stalks, so he has 5 rows * 80 stalks per row = 400 corn stalks.
  8 corn stalks will produce a bushel of corn, so Bob will harvest 400 corn stalks / 8 corn stalks per bushel = 50 bushels of corn.
