235. Найдите значение выражения -3,4 - m, если m = 8,3; m = 43; m = -17. 이 m=-1- 20' 30 m = -5;

а) m = 8,3: \[-3,4 - 8,3 = -11,7\]

б) m = \(\frac{4}{3}\) = 1\(\frac{1}{3}\): \[-3,4 - \frac{4}{3} = -3,4 - 1\frac{1}{3} = -3\frac{4}{10} - 1\frac{1}{3} = -3\frac{2}{5} - 1\frac{1}{3} = -3\frac{6}{15} - 1\frac{5}{15} = -4\frac{11}{15}\]

в) m = -1\(\frac{7}{30}\): \[-3,4 - (-1\frac{7}{30}) = -3,4 + 1\frac{7}{30} = -3\frac{4}{10} + 1\frac{7}{30} = -3\frac{2}{5} + 1\frac{7}{30} = -3\frac{12}{30} + 1\frac{7}{30} = -2\frac{30}{30} - \frac{12}{30} + 1\frac{7}{30} = -2\frac{18}{30} + 1\frac{7}{30} = -1\frac{48}{30} + \frac{7}{30} = -1\frac{41}{30} = -2\frac{11}{30}\]

г) m = -5: \[-3,4 - (-5) = -3,4 + 5 = 1,6\]
