chem the question once again

Answer 2

$\frac{ab}{cd} = \frac{5}{6} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ... \: (i) \\ \\ \frac{ac}{bd} = \frac{6}{7} \\ \frac{bd}{ac} = \frac{7}{6} \: \: \: \: \: \: ... \: (ii) (taking \: reciprocals) \\ \\ multiplying \: (i) \: and \: (ii) \\ \\ \frac{ab}{cd} \times \frac{bd}{ac} = \frac{5}{6} \times \frac{7}{6} \\ \frac{ {b}^{2} }{ {c}^{2} } = \frac{35}{36} \: \: \: \: \: \: \: \: \: \: \: ... \: (a \: and \: d\: cancel \: out)$

Hence, b²/c² = 35/36
