,if I push one side (of area A1) over a distance D1, the other side (of area A2) will raise a distance D2.
How to set it as a proportion? I'm in doubt between D1*A1=D2*A2 and D1/A1=D2/A2.
How do I figure which proportion is correct?

The fluid is incompressible. Therefore the volume displaced by depressing a piston mus displace the other piston through an equal volume. The volume displaced is piston travel times cross-sectional area.
A1D1 = A2D2, your first choice.
