I am struggling with this conversion and then I get a really tough question such as this,
here is the problem:
You are to administer Trazadone 450 mg po. The available unscored tablets are 200,100,50, and 25 mg. How many tablets and of which strength should you administer?
another question- can someone please explain all about conversion?Sadly I don't have a clue about how to do this sort of thing
Thank you for all your kindness in helping me out

You know, for this kind of a problem I would make a picture. Make four squares and label them "200", "100", "50", and "25". Think about what combinations of these you would use to come up with a total of 450. You are allowed to use multiples of the different squares.
The way to mathematically work this problem would be to divide 450 by the different strengths of tablets you have available.
450 divided 200 = 2.5
450 divided 100 = 4.5
450 divided 50 = 9
450 divided 25 = 18
There are multiple answers to this problem that would make it correct
Two 200 mg tablets + one 50 mg tablet
Two 200 mg tablets + two 25 mg tablets
Four 100 mg tablets + one 50 mg tablet
Four 100 mg tablets + two 25 mg tablets
Nine 50 mg tablets
Eighteen 25 mg tablets
you need 450 mg, The tablets are unscored so you cannot break them in half. You need to use as few as pills as possible. There is only one correct answer.
2 - 200 mg tablets, plus 1 - 50 mg tablet = 450 mg.
