PHYSICS HEELLPPP!!

Many people mistakenly believe that the astronauts who orbit the Earth are "above gravity." Calculate g for space shuttle territory, 225 kilometers above the Earth's surface (dashed line in sketch). Earth's mass is 6 1024 kg, and its radius is 6.38 106 m (6380 km).

The value is g is inversely proportional to the square of the distance from the center of the earth.
The sea level g is therefpre reduced by a factor
[6380/(6380+225)]^2 = 0.933
That make it 9.15 m/s^2 
Thank you so much for your help!!!

Hi I also have another question what would be the percentage of my answer of 9/8m/s^2? How do I calculate that to find my percentage?
