Accepted Answer

Решение:

$\frac{2}{5} + \frac{1}{10} = \frac{4}{10} + \frac{1}{10} = \frac{5}{10} = \frac{1}{2}$
$\frac{5}{6} + \frac{2}{3} = \frac{5}{6} + \frac{4}{6} = \frac{9}{6} = \frac{3}{2}$
$\frac{3}{4} + \frac{7}{12} = \frac{9}{12} + \frac{7}{12} = \frac{16}{12} = \frac{4}{3}$
$\frac{2}{15} + \frac{4}{5} = \frac{2}{15} + \frac{12}{15} = \frac{14}{15}$
$\frac{5}{7} + \frac{3}{14} = \frac{10}{14} + \frac{3}{14} = \frac{13}{14}$
$\frac{3}{11} + \frac{6}{55} = \frac{15}{55} + \frac{6}{55} = \frac{21}{55}$
$\frac{1}{6} + \frac{1}{9} = \frac{3}{18} + \frac{2}{18} = \frac{5}{18}$
$\frac{1}{10} + \frac{1}{15} = \frac{3}{30} + \frac{2}{30} = \frac{5}{30} = \frac{1}{6}$
$\frac{2}{8} + \frac{1}{12} = \frac{1}{4} + \frac{1}{12} = \frac{3}{12} + \frac{1}{12} = \frac{4}{12} = \frac{1}{3}$
$\frac{1}{9} + \frac{1}{2} = \frac{2}{18} + \frac{9}{18} = \frac{11}{18}$

Ответ: 1) $\frac{1}{2}$ 2) $\frac{3}{2}$ 3) $\frac{4}{3}$ 4) $\frac{14}{15}$ 5) $\frac{13}{14}$ 6) $\frac{21}{55}$ 7) $\frac{5}{18}$ 8) $\frac{1}{6}$ 9) $\frac{1}{3}$ 10) $\frac{11}{18}$
