Выполните вычитание:
1) $3\frac{1}{12} - \frac{1}{6}$;
2) $8\frac{7}{30} - 2\frac{9}{20}$;
3) $7\frac{10}{51} - 4\frac{21}{34}$;
4) $5\frac{1}{4} - 1\frac{3}{8}$.
$3\frac{1}{12} - \frac{1}{6} = 3\frac{1}{12} - \frac{2}{12} = 2\frac{13}{12} - \frac{2}{12} = 2\frac{11}{12}$
$8\frac{7}{30} - 2\frac{9}{20} = 8\frac{14}{60} - 2\frac{27}{60} = 7\frac{74}{60} - 2\frac{27}{60} = 5\frac{47}{60}$
$7\frac{10}{51} - 4\frac{21}{34} = 7\frac{20}{102} - 4\frac{63}{102} = 6\frac{122}{102} - 4\frac{63}{102} = 2\frac{59}{102}$
$5\frac{1}{4} - 1\frac{3}{8} = 5\frac{2}{8} - 1\frac{3}{8} = 4\frac{10}{8} - 1\frac{3}{8} = 3\frac{7}{8}$
