What percentage of 2.58*10^12 is 7.7*10^9?
Thanks!

If the question is "What percentage of x is y", then you would just divide x by y and multiply by 100 (y/x*100). So for instance, here we just put the numbers in and get 7.7*10^9/2.58*10^12= 0.002984496124031007751937984496124
multiply that by 100 and get:
0.2984496124031007751937984496124%
Hope that helps
