Пошаговое объяснение:

$\\ \frac{3.5 \times (5.26 + 3.44) \times 5.4}{(7.05 - 4.15) \times 14 \times 0.6} = \frac{3.5 \times 8.7 \times 5.4} {2.9 \times 14 \times 0.6} = \frac{3.5 \times 8.7 \times 9}{2.9 \times 14} = \frac{3.5 \times 3 \times 9}{14} = \frac{94.5}{14} = 6.75 = 6\frac{3}{4}$

$\\ \frac{1.5(20.1 - 7.3) \times 9.5}{(18.63 + 5.37) \times 3.2 \times 1.9} = \frac{1.5 \times 12.8 \times 9.5}{24 \times 3.2 \times 1.9} = \frac{0.46875 \times 12.8 \times 5}{24} = \frac{30}{24} = \frac{5}{4} = 1.25$
