Question

Помогите решить, пожалуйста

Answer 1

1) $\frac{6x}{5} =  \frac{18,48}{7} \\6x * 7 = 5 * 18,48\\6x * 7 = 92.4\\6x = \frac{92.4}{7}\\6x = 1[tex]1\frac{7}{8} :  \frac{5}{9} = x : \frac{4}{9}\\\frac{15}{8} *  \frac{9}{5} = x *  \frac{9}{4}\\ \frac{3}{8} *  \frac{9}{1} = x * \frac{9}{4}\\\frac{27}{8} = x *  \frac{9}{4}\\x = \frac{9}{4} : \frac{27}{8}\\x = \frac{9}{4} : \frac{8}{27}\\x = \frac{9}{4} * \frac{27}{8}\\x = \frac{243}{32}$3.2\\x = \frac{13.2}{6} \\x = 2[/tex]
