Вычислите:
а) $1\frac{4}{11} - 1$;
б) $1\frac{4}{11} - \frac{2}{11}$;
в) $1\frac{4}{11} - \frac{4}{11}$;
г) $1\frac{4}{11} - \frac{7}{11}$.
$1\frac{4}{11} - 1 = \frac{4}{11}$
$1\frac{4}{11} - \frac{2}{11} = 1\frac{2}{11}$
$1\frac{4}{11} - \frac{4}{11} = 1$
$1\frac{4}{11} - \frac{7}{11} = \frac{15}{11} - \frac{7}{11} = \frac{8}{11}$
