Выполните вычитание:
1) $4\frac{3}{16} - \frac{5}{8}$;
2) $6\frac{4}{9} - 3\frac{6}{7}$;
3) $10\frac{11}{24} - 8\frac{19}{36}$;
4) $9\frac{1}{6} - 5\frac{3}{4}$.
$4\frac{3}{16} - \frac{5}{8} = 4\frac{3}{16} - \frac{10}{16} = 3\frac{19}{16} - \frac{10}{16} = 3\frac{9}{16}$
$6\frac{4}{9} - 3\frac{6}{7} = 6\frac{28}{63} - 3\frac{54}{63} = 5\frac{91}{63} - 3\frac{54}{63} = 2\frac{37}{63}$
$10\frac{11}{24} - 8\frac{19}{36} = 10\frac{33}{72} - 8\frac{38}{72} = 9\frac{105}{72} - 8\frac{38}{72} = 1\frac{67}{72}$
$9\frac{1}{6} - 5\frac{3}{4} = 9\frac{4}{24} - 5\frac{18}{24} = 8\frac{28}{24} - 5\frac{18}{24} = 3\frac{10}{24} = 3\frac{5}{12}$
