  "Use ratio method. Tom:Willy = 1:6 and Tom:Zack = 2:3. Make Tom the same in both ratios by finding the LCM of 1 and 2.",
  "Multiply Tom:Willy by 2 -> 2:12. Combined: Tom:Willy:Zack = 2:12:3. Total = 17 units = 204, so 1 unit = 204 / 17 = 12.",
  "Tom = 2 x 12 = 24, Willy = 12 x 12 = 144, Zack = 3 x 12 = 36. Answer: Tom 24, Willy 144, Zack 36."
