Dosage Calc Format Problem

[S.Christopher]

Howdy!

My friend asked for some help with dosage calculation problems, but the format of the last two questions are throwing me off.

Could anyone give me a hand setting up these problems please?

1kg x 230lbs

2.2lbs

Cancel out the lbs and divide 230 by 2.2 and get 104.5 kg


2tabs x 250mg x 1gm =gm

---

1tab x 1000mg

tabs and mg cancels out. Reduce 250 to 1, and 1000 to 4.

reduce the left over 2/4 to 2grams.

I am left with 2grams and 104.5kg, but I don't understand what to do from this point on.

Start over completely. You're overcomplicating the problem like crazy.

So you know she weighs 104.5kg, and is taking 500mg / day. So what's her mg/kg (hint: / = divide)? Then when you get that number, all you have to do is convert it to g/kg by dividing the mg by 1,000.
