Ответ: a/c²

\frac{a}{b} = x \: \: \: \: \frac{b}{c} = \frac{2}{x} \: \: \: \: \: \frac{a}{c} = ?

Если a/b=x → b=a/x, то вместо b поставим a/x

\frac{a}{cx} = \frac{2}{x} \\ 2cx = ax \\ c = \frac{ax}{2x} = \frac{a}{2}

И вместо с поставим a/2

\frac{a}{c} = \frac{ \frac{a}{c} }{c} = \frac{a}{ {c}^{2} }
