Answer 1

Answer:

$3 : 4$

Step-by-step explanation:

$A = 2C \: and \: A = \frac{3}{2} B \\ so. \: \frac{A }{2} = C \: \: and \: \: \frac{2A}{3} = B \\ \\ ratio \: \: of \: C \: to \: B \\ = \frac{C}{B} = \frac{ \frac{A}{2} }{ \frac{2A}{3} } \\ = ( \frac{A}{2} \times \frac{3}{2A}) = \frac{3}{4} = 3: 4$
