conversations.value: This math problem has got me stumped: Billy and Tiffany are having a contest to see how can run the most miles in a week. On Sunday, Monday, and Tuesday, Billy runs 1 mile each day and Tiffany runs 2 miles each day. On Wednesday, Thursday, and Friday, Billy runs 1 mile each day and Tiffany runs a 1/3 of a mile each day. On Saturday Tiffany assumes she's going to win and takes the day off. How many miles does Billy have to run on Saturday to tie Tiffany?
  Can you show me the way?

conversations.value: Billy has already run 6 miles because 1 plus 1 plus 1 plus 1 plus 1 plus plus 1 equals 6
  Tiffany has already run 7 miles because 2 plus 2 plus 2 plus 1/3 plus 1/3 plus 1/3 equals 7
  Billy has to run 1 mile to tie Tiffany because 7 minus 6 equals 1.
