Question

\(\frac{6}{y}=\frac{-1}{4}=\frac{x}{-2}\) cho hỏi tính sao vậy

Answer 1

\(\frac{6}{y}=\frac{-1}{4}=\frac{x}{-2}\)

Ta có: \(\frac{6}{y}=\frac{-1}{4}\)

\(\Rightarrow y\left(-1\right)=6\cdot4\)

\(\Rightarrow y\left(-1\right)=24\)

\(\Rightarrow y=-24\)

Ta lại có: \(\frac{-1}{4}=\frac{x}{-2}\)

\(\Rightarrow4x=\left(-1\right)\cdot\left(-2\right)\)

\(\Rightarrow4x=2\)

\(\Rightarrow x=\frac{1}{2}\)

Answer 2

Ta có: \(\frac{6}{y}=-\frac{1}{4}\Rightarrow y=-\frac{6.4}{1}=-\frac{24}{1}=-24\)

Vậy: \(y=-24\)

Ta có: \(-\frac{1}{4}=\frac{x}{-2}\Rightarrow x=-\frac{1.-2}{4}=\frac{1}{2}\)

Vậy: \(x=\frac{1}{2}\)
