Geosynchronous orbit is 42 km from the center of the earth while the ISS orbits 7k km from the center of the earth.

...although I'm not sure that's right either. The point is that anything 42 km from the center is still very much inside the earth.

Sorry, dropped a k on that 42. Should be 42k km. Though there are clearly no calculations here, using the distance from the center of the earth is standard for gravitational calculation. It makes more sense to say that the ISS is 7000km/42000km=1/6th of the distance to a geosynchronous orbit than to say it's 400km/35000km=1/90th.
