ecoli Posted February 13, 2006 Share Posted February 13, 2006 first you have to convert 500 grams into miligrams. You can do this by multiplying by 1000. So, you have 500,000 milligrams. Now, simply divide by 10,000 and that's your answer. Link to comment Share on other sites More sharing options...

ecoli Posted February 17, 2006 Share Posted February 17, 2006 no problem... it's a simple calculation, but you have to think of it one step at a time. Link to comment Share on other sites More sharing options...
