Question

The pharmacist uses 67mg, 100g and 0.6 kg of drug to compound 3 separate precription. how much total drug did the pharmacist use in grams?

Answer 1

Answer: 700.067 g

Explanation:

Given : The pharmacist uses 67mg, 100g and 0.6 kg of drug to compound 3 separate prescription.

We know that 1 gram= 1000 milligram

and 1 kilogram = 1000 grams

Then, By UNITARY METHOD,
`\text{1 mg}=(1)/(1000)\text{ gram}`

Now, We convert each amount of drug into grams as ,

`67\ mg=67*(1)/(1000)\ g\\\\=0.067\text{ g}`

AND

`0.6\ kg=0.6*100=60\text{ g}`

Now, the total drug used by Pharmacist (in grams) =
`0.067+100+600=700.067\ g`

Hence, Pharmacist used 700.067 g of total drug.
