A pill weighs 70 mg. 7/9 of the pill is the active ingredient. How many milligrams are in the part of the pill that is not the active ingredient?

So if 7/9 is active that means 2/9 is not active.

I did 2 divided by 9 which gives me .22

I then multiplied 70 by .22 which gives me 15.4 mg.

I keep getting the answer wrong with this method. May someone please help me?

2/9 = 0.2222

0.2222 * 70 = 15.55
So my mistake was I didn't use enough digits after the decimal place?
That's the only I could see.
Ah, thank you. I really appreciate it. (:
You're very welcome.
