Ответ:

  1. \(160:(100:5)\cdot4=160:20\cdot4=8\cdot4=32\).
  2. \(303\cdot2-560=606-560=46\).
  3. \(8\cdot106-420=848-420=428\).
  4. \(350+640:8=350+80=430\).
  5. \(640:(8-4)\cdot5=640:4\cdot5=160\cdot5=800\).
  6. \(608:2+630:2=304+315=619\).
  7. \(76:2+76-38=38+76-38=76\).
  8. \(1200:4-320:4=300-80=220\).
  9. \(960-320:3=960-106\frac{2}{3}=853\frac{1}{3}\).
