conversations.value: Greg and Katie went to Mrs. Scarlet's gold store to have their gold chests opened. They realized Greg had four times less gold than Katie when Mrs. Scarlet opened the chests. If the total amount of gold is 100, how much gold does Greg have?
  Give me a detailed solution.

conversations.value: Let's say Greg had x number of golds.
  Katie had 4*x = 4x
  The total number of gold they all had is Katie's 4x+x gold for Gref = 5x
  If the total amount of gold, which was 100 = 5x
  Then x = 100/5=20
  Greg had x = 20 gold
