Вычислите:
а) $3\frac{3}{12} + \frac{5}{12}$;
б) $3\frac{3}{12} + 1\frac{5}{12}$;
в) $3\frac{3}{12} + \frac{11}{12}$;
г) $3\frac{3}{12} + 1\frac{11}{12}$.
$3\frac{3}{12} + \frac{5}{12} = 3\frac{8}{12} = 3\frac{2}{3}$
$3\frac{3}{12} + 1\frac{5}{12} = 4\frac{8}{12} = 4\frac{2}{3}$
$3\frac{3}{12} + \frac{11}{12} = 3\frac{14}{12} = 3\frac{7}{6} = 4\frac{1}{6}$
$3\frac{3}{12} + 1\frac{11}{12} = 4\frac{14}{12} = 5\frac{2}{12} = 5\frac{1}{6}$
