Вычислите сумму:
а) $5\frac{3}{5} + 1\frac{3}{5}$;
б) $3\frac{2}{7} + 2\frac{6}{7}$;
в) $4\frac{3}{8} + 7\frac{7}{8}$;
г) $9\frac{5}{9} + 11\frac{7}{9}$;
д) $1\frac{11}{17} + 2\frac{15}{17}$;
е) $4\frac{13}{27} + 8\frac{17}{27}$.
$5\frac{3}{5} + 1\frac{3}{5} = 6\frac{6}{5} = 6 + 1\frac{1}{5} = 7\frac{1}{5}$
$3\frac{2}{7} + 2\frac{6}{7} = 5\frac{8}{7} = 5 + 1\frac{1}{7} = 6\frac{1}{7}$
$4\frac{3}{8} + 7\frac{7}{8} = 11\frac{10}{8} = 11\frac{5}{4} = 11 + 1\frac{1}{4} = 12\frac{1}{4}$
$9\frac{5}{9} + 11\frac{7}{9} = 20\frac{12}{9} = 20\frac{4}{3} = 20 + 1\frac{1}{3} = 21\frac{1}{3}$
$1\frac{11}{17} + 2\frac{15}{17} = 3\frac{26}{17} = 3 + 1\frac{9}{17} = 4\frac{9}{17}$
$4\frac{13}{27} + 8\frac{17}{27} = 12\frac{30}{27} = 12\frac{10}{9} = 12 + 1\frac{1}{9} = 13\frac{1}{9}$
