Calculate the following: 6. Perform subtraction. a) $$1\frac{1}{8} - \frac{6}{8} = \frac{9}{8} - \frac{6}{8} = \frac{3}{8}$$ $$5\frac{2}{5} - \frac{3}{5} = \frac{27}{5} - \frac{3}{5} = \frac{24}{5}$$ $$4\frac{4}{9} - \frac{5}{6} = \frac{73}{9} - \frac{5}{6}$$ b) $$12\frac{5}{8} - 5\frac{11}{12}$$ $$3\frac{7}{16} - 1\frac{5}{8}$$ $$6\frac{2}{15} - 3\frac{2}{3}$$

6. Выполните вычитание.

1. \( 1\frac{1}{8} - \frac{6}{8} = \frac{9}{8} - \frac{6}{8} = \frac{3}{8} \)
2. \( 5\frac{2}{5} - \frac{3}{5} = \frac{27}{5} - \frac{3}{5} = \frac{24}{5} \)
3. \( 4\frac{4}{9} - \frac{5}{6} = \frac{40}{9} - \frac{5}{6} = \frac{80}{18} - \frac{15}{18} = \frac{65}{18} \)
4. \( 12\frac{5}{8} - 5\frac{11}{12} = 12\frac{15}{24} - 5\frac{22}{24} = 11\frac{39}{24} - 5\frac{22}{24} = 6\frac{17}{24} \)
5. \( 3\frac{7}{16} - 1\frac{5}{8} = 3\frac{7}{16} - 1\frac{10}{16} = 2\frac{23}{16} - 1\frac{10}{16} = 1\frac{13}{16} \)
6. \( 6\frac{2}{15} - 3\frac{2}{3} = 6\frac{2}{15} - 3\frac{10}{15} = 5\frac{17}{15} - 3\frac{10}{15} = 2\frac{7}{15} \)
