Question

Tính \(x:\)

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

Answer 1

Answer 2

Bài lúc nãy có 1 chút sai sót :))

\(x:4\dfrac{1}{3}=-2.5\)

=> \(x:\dfrac{13}{3}=-\dfrac{5}{2}\)

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

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