Answer 1

Ответ:

$6\frac{1}{2} :1\frac{6}{7}=\frac{13}{2}:\frac{13}{7}=\frac{13}{2}*\frac{7}{13} =\frac{1}{2}*\frac{7}{1} =\frac{7}{2}=3\frac{1}{2} =3,5$

$6\frac{2}{3}:2\frac{7}{9}=\frac{20}{3} :\frac{25}{9}=\frac{20}{3}*\frac{9}{25}=\frac{4}{1}*\frac{3}{5}=\frac{12}{5}=2\frac{2}{5}= 2,4$

$5\frac{3}{11}:2\frac{7}{11}=\frac{58}{11}:\frac{29}{11}=\frac{58}{11}*\frac{11}{29}=\frac{2}{1}*\frac{1}{1}=2$

$5\frac{1}{3}:3\frac{5}{9}=\frac{16}{3}:\frac{32}{9} =\frac{16}{3}*\frac{9}{32}=\frac{1}{1}*\frac{2}{2} =\frac{2}{2}=1$

$5\frac{5}{14}: 2\frac{1}{7} =\frac{75}{14} :\frac{15}{7} =\frac{75}{14}*\frac{7}{15}=\frac{5}{2}*\frac{1}{1}=\frac{5}{2} =2\frac{1}{2} =2,5$

$6\frac{2}{5}:1\frac{7}{9}=\frac{32}{5} :\frac{16}{9} =\frac{32}{5}*\frac{9}{16}=\frac{2}{5}*\frac{9}{1} =\frac{18}{5}=3\frac{3}{5}= 3,6$
