помогите срочно надооо​

Answer 1

$4:2\frac{2}{5}=4:\frac{12}{5} = 4*\frac{5}{12} =\frac{5}{4} =1\frac{2}{3} \\5\frac{5}{7} : 25= \frac{40}{7} :\frac{25}{1} = \frac{40}{7} * \frac{1}{25}=\frac{8}{7} *\frac{1}{5} =\frac{8}{35} \\4\frac{2}{7}:\frac{5}{7} =\frac{30}{7} *\frac{7}{5} =6\\6\frac{2}{3} :2\frac{4}{7} =\frac{20}{3} :\frac{18}{7} =\frac{20}{3}*\frac{7}{18}=\frac{70}{27} =2\frac{16}{27}\\1\frac{1}{4} :1\frac{2}{3}=\frac{5}{4} *\frac{3}{5} =\frac{3}{4} =0,75$
