Answer 1

=>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

Answer 2

 

\(\frac{x}{4}=\frac{15}{y}=\frac{z}{64}=\frac{6}{8}\)

\(\frac{x}{4}=\frac{6}{8}\Rightarrow x=\frac{4\cdot6}{8}=3\)

\(\frac{15}{y}=\frac{6}{8}\Rightarrow y=\frac{15\cdot8}{6}=20\)

\(\frac{z}{64}=\frac{6}{8}\Rightarrow x=\frac{64\cdot6}{8}=48\)
