looking at the first ratio: yz: zx = 1:2 can assume z is nonzero zx:xy = 2:3 can also assume x is nonzero \[\frac{ yz }{ zx }=\frac{ y }{ x }=\frac{ 1 }{ 2 }\]means y = (1/2)x looking at the second ratio: \[\frac{ x }{ yz }:\frac{ y }{ zx }=1:k\] can factor out the 1/z to get \[\frac{ x }{ y }:\frac{ y }{ x }=1:k\] meaning \[\frac{ \frac{ x }{ y } }{ \frac{ y }{ x } }=\frac{ x^{2} }{ y^{2} }=\frac{ 1 }{ k }\] \[\frac{ x^{2} }{ (\frac{ 1 }{ 2 }x) ^{2}}=\frac{ 1 }{ k }=4\] k = 1/4

Vocaloid:

@smokeybrown would you mind checking this, I'm not 100% confident on my work

SmokeyBrown:

Yeah that makes sense, I think it's right.
