Ответ:
- \(2.5 \cdot 2.7 \cdot 4 = 6.75 \cdot 4 = 27\).
- \(3.9 \cdot 0.5 \cdot 2 = 3.9 \cdot 1 = 3.9\).
- \(1.25 \cdot 1.9 \cdot 8 = 1.25 \cdot 8 \cdot 1.9 = 10 \cdot 1.9 = 19\).
- \(4 \cdot 5.6 \cdot 0.25 = 4 \cdot 0.25 \cdot 5.6 = 1 \cdot 5.6 = 5.6\).
- \(0.5 \cdot 30 \cdot 0.1 = 15 \cdot 0.1 = 1.5\).
Ответ: 27; 3,9; 19; 5,6; 1,5.
