Question 22856: Hello, My ame is Delores Pack
I'm not that good in math, so I came to place that probably can help me.
I'm struggling, and getting stressed out.
1. How many 0.0125 grain doses can be made from 3/8 grains of a drug?

2. A formula for 1000 tablets contains 11.5 grams of an antihistamine. How many grams of the antihistamine should be used to prepare 475 tablets?
3. If a syringe contains 28 mg of drug in 3 ml how many milligrams of the drug would a patient receive if 1.2 ml is administered?

1)
First convert 3/8 to a decimal. Just divide 3 by 8 to get 0.375.
Next, you need to find out how many times does 0.0125 go into 0.375, so this is a division problem.

Answer: You can get thirty 0.0125-grain doses from 3/8 grains of a drug.
2)
If 1000 tablets contain 11.5 grams of an antihistamine, you need to find out how much antihistamine 1 tablet contains. Do it like this:
(1000 tablets)/1000 = 11.5 grams/1000
1 tablet = 0.0115 grams Now, to find out how much antihistamine is in 475 tablets, do it like this:
1 tablet = 0.0115 grams
475 (1 tablet) = 475(0.0115) grams
475 tablets = 5.4625 grams of antihistamine.
3) You can use proportions on this problem.
Solve for x. Multiply both sides of the equation by 1.2ml
Do the math.

Answer: The patient would receive 11.2 mg of the drug.
