Вычислите:
а) $\frac{24}{33} - \frac{13}{33}$;
б) $\frac{5}{21} + \frac{2}{21}$;
в) $\frac{14}{27} + \frac{4}{27}$;
г) $\frac{16}{35} + \frac{12}{35}$.
$\frac{24}{33} - \frac{13}{33} = \frac{24 - 13}{33} = \frac{11}{33} = \frac{1}{3}$
$\frac{5}{21} + \frac{2}{21} = \frac{5 + 2}{21} = \frac{7}{21} = \frac{1}{3}$
$\frac{14}{27} + \frac{4}{27} = \frac{14 + 4}{27} = \frac{18}{27} = \frac{2}{3}$
$\frac{16}{35} + \frac{12}{35} = \frac{28}{35} = \frac{4}{5}$
