Answer 2

Конечно, давайте рассчитаем каждое выражение поочередно:

1. \(0.125 \times 5 + \frac{1}{3} \times \frac{3}{4}\) \(= 0.625 + \frac{1}{4}\) \(= 0.625 + 0.25\) \(= 0.875\)

2. \(\frac{4}{7} \times \frac{21}{32} \times \frac{8}{9}\) \(= \frac{672}{2016}\) \(= \frac{1}{3}\)

3. \(1 + \frac{5}{27} \times \left(\frac{3}{4}\)^2 \times 6\) \(= 1 + \frac{5}{27} \times \frac{9}{16} \times 6\) \(= 1 + \frac{5}{27} \times \frac{54}{16}\) \(= 1 + \frac{15}{16}\) \(= \frac{31}{16}\)

4. \(0.375 \times 9 + \frac{1}{3} \times \frac{2}{7}\) \(= 3.375 + \frac{2}{21}\) \(= \frac{71}{21} \approx 3.381\)

Итак, результаты выражений:

1. \(0.125 \times 5 + \frac{1}{3} \times \frac{3}{4} = 0.875\) 2. \(\frac{4}{7} \times \frac{21}{32} \times \frac{8}{9} = \frac{1}{3}\) 3. \(1 + \frac{5}{27} \times \left(\frac{3}{4}\)^2 \times 6 = \frac{31}{16}\) 4. \(0.375 \times 9 + \frac{1}{3} \times \frac{2}{7} \approx 3.381\)
