Вычислите сумму:
а) $9\frac{2}{3} + 1\frac{1}{4}$;
б) $13\frac{1}{5} + 4\frac{2}{7}$;
в) $2\frac{3}{10} + 6\frac{1}{9}$;
г) $4\frac{2}{3} + 7\frac{4}{5}$;
д) $7\frac{3}{20} + 8\frac{4}{5}$;
е) $2\frac{7}{48} + 11\frac{77}{96}$.
$9\frac{2}{3} + 1\frac{1}{4} = 10 + \frac{8 + 3}{12} = 10\frac{11}{12}$
$13\frac{1}{5} + 4\frac{2}{7} = 17 + \frac{7 + 10}{35} = 17\frac{17}{35}$
$2\frac{3}{10} + 6\frac{1}{9} = 8 + \frac{27 + 10}{90} = 8\frac{37}{90}$
$4\frac{2}{3} + 7\frac{4}{5} = 11 + \frac{10 + 12}{15} = 11\frac{22}{15} = 11 + 1\frac{7}{15} = 12\frac{7}{15}$
$7\frac{3}{20} + 8\frac{4}{5} = 15 + \frac{3 + 16}{20} = 15\frac{19}{20}$
$2\frac{7}{48} + 11\frac{77}{96} = 13 + \frac{14 + 77}{96} = 13\frac{91}{96}$
