\(\frac{8}{12}=\frac{2}{3}=\frac{x}{3}=\frac{14}{21}=\frac{14}{y}=\frac{40}{60}=\frac{z}{60}\Rightarrow x=2;y=21;z=40.\)
Ta có
\(\frac{x}{3}=\frac{14}{y}=\frac{z}{60}=\frac{8}{12}\)
=> \(\frac{14}{y}=\frac{x}{3}=\frac{z}{60}=\frac{8}{12}\)
=> z = 8 . 60 : 12 = 40
=> x = 40 . 3 : 60 = 2
=> y = 3 . 14 : 2 = 21
Vậy, x = 2 ; y = 21 ; z = 40
