You see,my mom didn't have to learn this.And when I showed her the rest of my answers,she told me to post this.

So...
0.009 kg = 9000 mg ??
0.2 mg = 0.0002 g ??
8.6 kg = 8600 g ??
800 g = 800 000 mg ??
1.7 kg = 1700 g ??
She said to post this.She doesn't really think they are right...This is really her question...So...Can someone answer this for her?

I'm sorry your Mom didn't have to learn this.

Your first answer is correct.

To check the rest of your answers, go to Google and type in the problems in this format:

0.2 mg = ? g
