[tex]1) 3\frac{4}{5} - 2\frac{3}{5} = 1\frac{1}{5} = 1,2\\\\3) 4\frac{5}{6} - 2\frac{5}{12} = 4\frac{10}{12} - 2\frac{5}{12} = 2\frac{5}{12} \\\\5) 9\frac{1}{2} - 2\frac{1}{4} = 9\frac{2}{4} - 2\frac{1}{4} = 7\frac{1}{4} = 7,25\\\\7) 11\frac{3}{7} - 5\frac{1}{3} = 11\frac{9}{21} - 5\frac{7}{21} = 6\frac{2}{21}[/tex]
