Помогите решить математическую грамотность

Answer 1

$2r-p\ \textless \ 0 =\ \textgreater \ |2r-p|=p-2r \\ p-2q+r\ \textless \ 0 =\ \textgreater \ |p-2q+r|=-p+2q-r \\ q\ \textgreater \ 0 =\ \textgreater \ |q| = q \\ r\ \textless \ 0, |r| = -r$
$\frac{|2r-p|+|p-2q+r|-2|q|}{|r|}= \frac{p-2r-p+2q-r-2q}{-r}= \frac{-3r}{-r}=3$
