Question

Cho -4/8=x/-10=-7/y=z/-3. Tìm các số nguyên x,y,z

Answer 1

Giải:

\(\dfrac{-4}{8}=\dfrac{x}{-10}=\dfrac{-7}{y}=\dfrac{z}{-3}\) 

\(\Rightarrow\dfrac{-4}{8}=\dfrac{x}{-10}\) 

\(\Rightarrow x=\dfrac{-10.-4}{8}=5\) 

\(\Rightarrow\dfrac{-4}{8}=\dfrac{-7}{y}\) 

\(\Rightarrow y=\dfrac{-7.8}{-4}=14\) 

\(\Rightarrow\dfrac{-4}{8}=\dfrac{z}{-3}\) 

\(\Rightarrow z=\dfrac{-4.-3}{8}=\dfrac{3}{2}\)
