201. Вычисли: 6000 : (25 · 4) · 7; 6000 : (900 : 3) · 6; 832 − 328 − 247; 603 − (347 − 189); 903 − (178 + 359); 324 + (503 − 294).

1. \(6000:(25\cdot4)\cdot7=6000:100\cdot7=60\cdot7=420\).
2. \(6000:(900:3)\cdot6=6000:300\cdot6=20\cdot6=120\).
3. \(832-328-247=504-247=257\).
4. \(603-(347-189)=603-158=445\).
5. \(903-(178+359)=903-537=366\).
6. \(324+(503-294)=324+209=533\).

Ответ: 420; 120; 257; 445; 366; 533.
