Another gravitation problem

In the end there was no complicated calculation. It was way more simple than I thought. I felt like I just watched a suspense thriller. Thank you guys very much for helping me.

You got there in the end, but effectively all you had to do was:

Gravitational acceleration -> inverse square law -> 3x distance -> (1/3) squared = 1/9 x acceleration -> 9.81/9 = 1.09

You should really be thanking Perok and BvU, not me.

If you promise to work with symbols as much as you can I'm more than rewarded...
