Question

Tìm \(x:\)

\(x:4\dfrac{1}{3}=-2,5\)

Answer 1

\(x:4\dfrac{1}{3}=-2,5\)

\(\Leftrightarrow x:\dfrac{13}{3}=-2,5\)

\(\Leftrightarrow x=-2,5.\dfrac{13}{3}\)

\(\Leftrightarrow x=-\dfrac{65}{6}\)

Answer 2

\(x:4\dfrac{1}{3}=-2,5\Rightarrow x:\dfrac{13}{3}=-2,5\Rightarrow x=-2,5.\dfrac{13}{3}\Rightarrow x=-\dfrac{65}{6}\)

Answer 3

Ta có: \(x:4\dfrac{1}{3}=-2.5\)

\(\Leftrightarrow x:\dfrac{13}{3}=-\dfrac{5}{2}\)

\(\Leftrightarrow x=\dfrac{-5}{2}\cdot\dfrac{13}{3}=\dfrac{-65}{6}\)

Vậy: \(S=\left\{-\dfrac{65}{6}\right\}\)
