1) $5\frac{8}{51} - 3\frac{5}{17}^{/3} = 5\frac{8}{51} - 3\frac{15}{51} = 4\frac{59}{51} - 3\frac{15}{51} = $
2) $4\frac{2}{9} - 1\frac{17}{36} = $
3) $6\frac{2}{3} - 2\frac{6}{7} = $
4) $3\frac{1}{6} - 2\frac{3}{8} = $
5) $9\frac{7}{20} - 4\frac{9}{25} = $
6) $7\frac{4}{15} - 5\frac{5}{9} = $
$5\frac{8}{51} - 3\frac{5}{17}^{/3} = 5\frac{8}{51} - 3\frac{15}{51} = 4\frac{59}{51} - 3\frac{15}{51} = 1\frac{44}{51}$
$4\frac{2}{9}^{/4} - 1\frac{17}{36} = 4\frac{8}{36} - 1\frac{17}{36} = 3\frac{44}{36} - 1\frac{17}{36} = 2\frac{27}{36} = 2\frac{3}{4}$
$6\frac{2}{3}^{/7} - 2\frac{6}{7}^{/3} = 6\frac{14}{21} - 2\frac{18}{21} = 5\frac{35}{21} - 2\frac{18}{21} = 3\frac{17}{21}$
$3\frac{1}{6}^{/4} - 2\frac{3}{8}^{/3} = 3\frac{4}{24} - 2\frac{9}{24} = 2\frac{28}{24} - 2\frac{9}{24} = \frac{19}{24}$
$9\frac{7}{20}^{/5} - 4\frac{9}{25}^{/4} = 9\frac{35}{100} - 4\frac{36}{100} = 8\frac{135}{100} - 4\frac{36}{100} = 4\frac{99}{100}$
$7\frac{4}{15}^{/3} - 5\frac{5}{9}^{/5} = 7\frac{12}{45} - 5\frac{25}{45} = 6\frac{57}{45} - 5\frac{25}{45} = 1\frac{32}{45}$
