a) \(-2 \frac{5}{8} - 1 \frac{1}{4} = -2 \frac{5}{8} - 1 \frac{2}{8} = -3 \frac{7}{8}\) б) \(3 \frac{1}{8} - (-2 \frac{1}{6}) = 3 \frac{1}{8} + 2 \frac{1}{6} = 3 \frac{3}{24} + 2 \frac{4}{24} = 5 \frac{7}{24}\) г) \(-3 \frac{7}{12} - (-1 \frac{3}{8}) = -3 \frac{7}{12} + 1 \frac{3}{8} = -3 \frac{14}{24} + 1 \frac{9}{24} = -2 \frac{5}{24}\) д) \(-3 \frac{1}{4} - 0,75 = -3,25 - 0,75 = -4\) e) \(-2,4 - (-1 \frac{1}{3}) = -2,4 + 1 \frac{1}{3} = -2,4 + 1,333... = -1,0666... \approx -1,07\) ж) \(3 \frac{2}{11} - 4 \frac{4}{33} = 3 \frac{6}{33} - 4 \frac{4}{33} = -1 \frac{-2}{33} = -1 \frac{2}{33}\) з) \(-4 \frac{1}{9} - (-3 \frac{5}{6}) = -4 \frac{2}{18} + 3 \frac{15}{18} = -1 \frac{-13}{18} = - \frac{13}{18}\)
