Решите задачу:

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