Решение:
- \( 42 : 7 \cdot 8 = 6 \cdot 8 = 48 \)
- \( 60 \cdot 5 : 10 = 300 : 10 = 30 \)
- \( 630 : 9 \cdot 3 = 70 \cdot 3 = 210 \)
- \( 72 : 8 \cdot 3 = 9 \cdot 3 = 27 \)
- \( 44 : 4 \cdot 2 = 11 \cdot 2 = 22 \)
- \( 360 : 4 \cdot 3 = 90 \cdot 3 = 270 \)
- \( 12 \cdot 3 : 9 = 36 : 9 = 4 \)
- \( 46 : 2 \cdot 3 = 23 \cdot 3 = 69 \)
- \( 280 : 4 \cdot 7 = 70 \cdot 7 = 490 \)
Ответ: 48, 30, 210, 27, 22, 270, 4, 69, 490.
