Ответ:
- \(47.3 \cdot 0.6 + 21.5 = 28.38 + 21.5 = 49.88\).
- \((58.2 - 27.6) \cdot 0.5 = 30.6 \cdot 0.5 = 15.3\).
- \(7.25 \cdot (0.4 \cdot 5) = 7.25 \cdot 2 = 14.5\).
- \((81 : 0.9) \cdot (5.6 : 14) = 90 \cdot 0.4 = 36\).
- \((712.4 - 58.7 \cdot 2) : 5 = (712.4 - 117.4) : 5 = 595 : 5 = 119\).
Ответ: 1) 49,88; 2) 15,3; 3) 14,5; 4) 36; 5) 119.
