a, 6.15 = 2.45 b, -0,125.16 = 0,4.(-5)
\(\Rightarrow\frac{6}{2}=\frac{45}{15}\) \(\Rightarrow\frac{-0,125}{0,4}=\frac{-5}{16}\)
\(\Rightarrow\frac{2}{6}=\frac{15}{45}\) \(\Rightarrow\frac{0,4}{-0,125}=\frac{16}{-5}\)
\(\Rightarrow\frac{-0,125}{-5}=\frac{0,1}{16}\)
\(\Rightarrow\frac{6}{45}=\frac{2}{15}\) \(\Rightarrow\frac{-5}{-0,125}=\frac{16}{0,4}\)
\(\Rightarrow\frac{45}{6}=\frac{15}{2}\)
mình làm rồi nhưng chiều tớ mới nhắn đc hông.
