292. Perform the calculations.

Решение:

Выполним вычисления:

1. \( 68432 \div 94 = 728 \)
2. \( 20703 \div 67 = 309 \)
3. \( 812 \times 907 = 736484 \)
4. \( 470 \times 302 = 141940 \)
5. \( 564 \times 70 - 564 \times 60 = 564 \times (70 - 60) = 564 \times 10 = 5640 \)
6. \( 809 \times 62 + 809 \times 38 = 809 \times (62 + 38) = 809 \times 100 = 80900 \)

Ответ: 728, 309, 736484, 141940, 5640, 80900.
