Б) 4\(\frac{3}{8}\)-3\(\frac{3}{7}\)-9,5+5\(\frac{1}{8}\)
Ответ:
Решение:
\(4\frac{3}{8}-3\frac{3}{7}-9,5+5\frac{1}{8} = (4\frac{3}{8}+5\frac{1}{8}) - 3\frac{3}{7} - 9,5 = 9\frac{4}{8} - 3\frac{3}{7} - 9,5 = 9\frac{1}{2} - 3\frac{3}{7} - 9\frac{1}{2} = -3\frac{3}{7} = -\frac{24}{7}\)
Ответ: -\( \frac{24}{7} \)
