Решим каждый пример по порядку:
- (1.1 - 2.7) × 4.5 = -1.6 × 4.5 = -7.2
- -5.5 + 6.5 × 7.4 = -5.5 + 48.1 = 42.6
- 35 × (1.2 - 3.5) = 35 × (-2.3) = -80.5
- (-6 + 4.5) × 7.2 = -1.5 × 7.2 = -10.8
- (0.375 - 3) × 16 = -2.625 × 16 = -42
- 2.5 - 6.5 × 2.4 = 2.5 - 15.6 = -13.1
- -5.2 - 5.5 × 3.2 = -5.2 - 17.6 = -22.8
- (4.4 - 9.8) : 27 = -5.4 : 27 = -0.2
- -5.7 + 3.23 : 1.9 = -5.7 + 1.7 = -4
- 2.4 - 8.12 : 2.8 = 2.4 - 2.9 = -0.5
- 8.06 : 6.2 - 7.1 = 1.3 - 7.1 = -5.8
- 29 : (6.1 - 8.6) = 29 : (-2.5) = -11.6
- (-5.3 + 1.7) : 1.5 = -3.6 : 1.5 = -2.4
- (-2 + 5.2) : 16 = 3.2 : 16 = 0.2
- -1.8 - 3.99 : 2.1 = -1.8 - 1.9 = -3.7
