\(\frac{a+5}{a-5}=\frac{b+6}{b-6}\Rightarrow\left(a+5\right)\left(b-6\right)=\left(a-5\right)\left(b+6\right)\)
\(\Leftrightarrow ab-6a+5b-30=ab+6a-5b-30\)
\(\Leftrightarrow12a=10b\Leftrightarrow\frac{a}{b}=\frac{10}{12}=\frac{5}{6}\)
Cho \(\frac{a+5}{a-5}=\frac{b+6}{b-6}\) ( với \(a\ne5\text{ , }b\ne6\) )
Tính tỉ số \(\frac{a}{b}\)
\(Cho\frac{a+5}{a-5}=\frac{b+6}{b-6}\left(a\ne5,b\ne6\right).Cmr\frac{a}{b}=\frac{5}{6}\)
Cho \(\frac{a+5}{a-5}=\frac{b+6}{b-6}\) \(\left(a\ne5,b\ne6\right)\). Như vậy tỉ số \(\frac{a}{b}\) bằng .....
