Вычислите:
а) $4\frac{5}{16} - 1\frac{3}{8}$;
б) $8\frac{6}{25} - 3\frac{4}{5}$;
в) $12\frac{2}{15} - 2\frac{1}{5}$;
г) $18\frac{14}{45} - 1\frac{7}{15}$;
д) $27\frac{2}{39} - 6\frac{5}{13}$;
е) $23\frac{9}{34} - 2\frac{7}{17}$.
$4\frac{5}{16} - 1\frac{3}{8} = 4\frac{5}{16} - 1\frac{6}{16} = 3\frac{21}{16} - 1\frac{6}{16} = 2\frac{15}{16}$
$8\frac{6}{25} - 3\frac{4}{5} = 8\frac{6}{25} - 3\frac{20}{25} = 7\frac{31}{25} - 3\frac{20}{25} = 4\frac{11}{25}$
$12\frac{2}{15} - 2\frac{1}{5} = 12\frac{2}{15} - 2\frac{3}{15} = 11\frac{17}{15} - 2\frac{3}{15} = 9\frac{14}{15}$
$18\frac{14}{45} - 1\frac{7}{15} = 18\frac{14}{45} - 1\frac{21}{45} = 17\frac{59}{45} - 1\frac{21}{45} = 16\frac{38}{45}$
$27\frac{2}{39} - 6\frac{5}{13} = 27\frac{2}{39} - 6\frac{15}{39} = 26\frac{41}{39} - 6\frac{15}{39} = 20\frac{26}{39} = 20\frac{2}{3}$
$23\frac{9}{34} - 2\frac{7}{17} = 23\frac{9}{34} - 2\frac{14}{34} = 22\frac{43}{34} - 2\frac{14}{34} = 20\frac{29}{34}$
