[tex] \frac{V2}{V1} = \frac{P2}{P1} [/tex]

It's usually because there's a linear relationship like

[tex] P = k V [/tex]

that underlies it, where k is some constant of proportionality. When you "stack" the equation, the proportionality constant drops out:

[tex] \frac{\rlap{\backslash} k V2}{\rlap{\backslash} k V1} = \frac{P2}{P1} [/tex]
