Answer 2

mờ vaiiiii

Answer 3

\(a,x.\dfrac{14}{27}=-\dfrac{7}{9}\)

\(x=-\dfrac{7}{9}:\dfrac{14}{27}\)

\(x=-\dfrac{3}{2}\)

 

\(c,\dfrac{2}{5}:x=\dfrac{1}{16}:0,125\)

\(\dfrac{2}{5}:x=\dfrac{1}{2}\)

\(x=\dfrac{2}{5}:\dfrac{1}{2}\)

\(x=\dfrac{4}{5}\)

Sai thì cho thông cảm ạ ! Vì số mờ quá bạn.
