Пошаговое объяснение:

1)

$\frac{(0.63 \times 10 - 3.8 \div 0.8) \div 15.5}{8.925 \div 52.5 + 0.08} = \\ = \frac{(6.3 - 4.75) \div 15.5}{8.925 \div 52.5 + 0.08} = \\ = \frac{1.55 \div 15.5}{8.925 \div 52.5 + 0.08 } = \\ = \frac{0.1}{0.17 + 0.08} = \\ = \frac{0.1}{0.25} = \frac{2}{5} = \\ = 0.4$

2)

$\frac{23.65 \times 1.4 - 18.212 \div 5.8 + 0.03}{(108.25 + 62.75) \div 28.5} = \\ = \frac{33.11 - 3.14 + 0.03}{(108.25 + 62.75) \div 28.5} = \\ = \frac{30}{171 \div 28.5} = \\ = \frac{30}{6} = 5$

3)

$\frac{(12.42 \div 2.7 \div 4 + 41) \times 0.14 - 4.8}{(28 - 11 \times 0.5 \div 5 - 16.9) \times 0.1} = \\ = \frac{(1.15 + 41) \times 0.14 - 4.8}{(28 - 1.1 - 16.9) \times 0.1} = \\ = \frac{42.15 \times 0.14 - 4.8}{10 \times 0.1} = \\ = \frac{5.901 - 4.8}{1} = \\ = \frac{1.101}{1} = 1.101$

4

$\frac{1.25 \times 0.18 + 28.7 \div 41 + 0.075}{3.52 - (2.07 + 9 \div 7.5)} = \\ = \frac{0.225 + 0.7 + 0.075}{3.52 - (2.07 + 1.2)} = \\ = \frac{0.225 + 0.7 + 0.075}{3.52 - 2.07 - 1.2} = \\ = \frac{1}{0.25} = 4$
