Tìm x, y, z biết: x/4=-9/y=z/8=-24/32
Giải thích
\(\frac{x}{4} = \frac{{ - 24}}{{32}} \Rightarrow x = \frac{{ - 24.4}}{{32}} = - 3\)
\[\frac{{ - 9}}{y} = \frac{{ - 24}}{{32}} \Rightarrow y = \frac{{ - 9.32}}{{ - 24}} = 12\]
\(\frac{z}{8} = \frac{{ - 24}}{{32}} \Rightarrow z = \frac{{ - 24.8}}{{32}} = - 6\)
