@iGreen  could you help, please? :)

I believe it's 0.05 because that's how much the person must've rounded it.

Ok, do you mind explaining how you got that answer? The only thing I am confused on with these problems is how to set them up. I know that the equation for GPE= half of the nearest unit rounded to (in this case .5x.1) and then would I do that over the measuerment?

53.9
  0.05

Look, 53.9 doesn't have a placement after the number 9..so it would have to be 0.05..because there had to be a number after 53.9..
