Question

tìm x,y,z bt:

  12/6=x/5=y/3=z/17

Answer 1

\(\hept{\Rightarrow\begin{cases}\frac{x}{5}=2\Rightarrow x=10\\\frac{y}{3}=2\Rightarrow y=6\\\frac{z}{17}=2\Rightarrow z=34\end{cases}}\)

Answer 2

\(\frac{12}{6}=\frac{x}{5}=\frac{y}{3}=\frac{z}{17}\)

\(\Rightarrow\frac{x}{5}=\frac{y}{3}=\frac{z}{17}=2\)

\(\Rightarrow x=2.5=10\)

\(y=3.2=6\)

\(z=17.2=34\)
