What is the gravitational force vetween 2 15kg packages that are 35cm apart? What fraction is this of the weight of one package?

Is there some reason you cant compute Gravitaional force
F=GM2M1/distance^2 
i used this equation to solve the problem but i keep coming up to 8.1 x 10^9, but according to my teacher's answer, it is 8.2 x 10^8

Recheck your work.

IF you post your work, I will check it for you.
