Question

Вопрос:

Accepted Answer

\(9+\frac{3}{17}=9\frac{3}{17}\).
\(\frac{9}{72}+5=\frac{1}{8}+5=5\frac{1}{8}\), поскольку \(\frac{9}{72}=\frac{1}{8}\).
\(4\frac{5}{18}+2\frac{4}{18}=(4+2)+\frac{5+4}{18}=6\frac{9}{18}=6\frac{1}{2}\).
\(6\frac{7}{15}-2\frac{3}{15}=(6-2)+\frac{7-3}{15}=4\frac{4}{15}\).
\(9\frac{11}{16}+\frac{3}{16}-2\frac{2}{16}=9\frac{14}{16}-2\frac{2}{16}=7\frac{12}{16}=7\frac{3}{4}\).
\(15\frac{7}{10}+2\frac{2}{10}-4\frac{1}{10}=17\frac{9}{10}-4\frac{1}{10}=13\frac{8}{10}=13\frac{4}{5}\).

Ответ: 1) 9 3/17; 2) 5 1/8; 3) 6 1/2; 4) 4 4/15; 5) 7 3/4; 6) 13 4/5.
