Answer 1

$10 frac{ 5 }{18} - 5 frac{8}{27} = 5 frac{15 - 16}{54} = 4 frac{69 - 16}{54} = 4 frac{53}{54}$
$32 frac{8}{21} - 23 frac{7}{15} = 9 frac{40 - 49}{105} = 8 frac{145 - 49}{105} = 8 frac{96}{105} = 8 frac{32}{35}$
$41 frac{9}{28} - 15 frac{2}{21} = 26 frac{27 - 8}{84} = 26 frac{19}{84}$
$58 frac{11}{20} - 22 frac{29}{35} = 36 frac{77 - 116}{140} = 35 frac{217 - 116}{140} = 35 frac{101}{140}$
