Calculating magnification

MFT crop factor 2

working distance = 20 cm

Olympus M.Zuiko digital ED 12-100mm 4.0 @100mm

Olympus M.Zuiko digital ED 60mm @60mm

How can I calulate the size of the subject on the sensor?

I know the 60mm is 1:1. (1-time magnification)

Is the 100mm then 1:0.6? (1.6 time manification) ?
