T: $$5\frac{3}{8}-2\frac{5}{8} = 4\frac{11}{8} - 2\frac{5}{8} = 2\frac{6}{8} = 2\frac{3}{4}$$

K: $$9\frac{10}{17}-4\frac{15}{17} = 8\frac{27}{17} - 4\frac{15}{17} = 4\frac{12}{17}$$

E: $$4\frac{19}{29}-2\frac{23}{29} = 2\frac{19-23}{29} = 4\frac{19}{29}-2\frac{23}{29} = 3\frac{48}{29} - 2\frac{23}{29} = 1\frac{25}{29}$$

Л: $$16\frac{11}{17}-10\frac{15}{17} = 15\frac{28}{17} - 10\frac{15}{17} = 5\frac{13}{17}$$

Г: $$2\frac{7}{18}-1\frac{11}{18} = 1\frac{25}{18} - 1\frac{11}{18} = \frac{14}{18} = \frac{7}{9}$$
