Ответ:

  1. \(6\,000 : (20 \cdot 5) \cdot 6 = 6\,000 : 100 \cdot 6 = 60 \cdot 6 = 360\).
  2. \(6\,000 : (90 : 9) \cdot 100 = 6\,000 : 10 \cdot 100 = 600 \cdot 100 = 60\,000\).
  3. \((525 - 238) \cdot 3 = 287 \cdot 3 = 861\).
  4. \((517 - 450) \cdot 0 = 67 \cdot 0 = 0\).
  5. \((924 - 207) : 3 = 717 : 3 = 239\).
  6. \((413 + 196) : 7 = 609 : 7 = 87\).
