conversations.value: I'm stuck on this math problem: Mark and James need a total of 14 dice that are 12 sided to play their game.  Mark has a bag of 10 dice and 60% of them are 12 sided.  James has a bag of 8 dice and 75% of them are 12 sided.  How many dice will the boys need to buy to play their game?
  Can you help?

conversations.value: Mark has 60% 12 sided dice, so 60/100 * 10 dice in his bag = 6 12 sided dice.
  James has 75% 12 sided dice, so 75/100 * 8 dice in his bag = 6 12 sided dice.
  They will need to purchase 14 dice - 6 dice - 6 dice = 2 dice.
