=>2x/8=6/8=>2x=6=>x=3=>3/4=15/y=>15/20=15/y=>y=20
z/64=6/8=>z/64=48/64=>z=48
l-i-k-e cho mk nha
\(\frac{x}{4}=\frac{15}{y}=\frac{z}{64}=\frac{6}{8}\)
\(\frac{x}{4}=\frac{6}{8}\Rightarrow x=\frac{4\cdot6}{8}=3\)
\(\frac{15}{y}=\frac{6}{8}\Rightarrow y=\frac{15\cdot8}{6}=20\)
\(\frac{z}{64}=\frac{6}{8}\Rightarrow x=\frac{64\cdot6}{8}=48\)
