The pharmacist uses 67mg, 100g and 0.6 kg of drug to compound 3 separate precription. how much total drug did the pharmacist use
FromTheMoon [43]

Answer: 700.067 g

Step-by-step 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}=\dfrac{1}{1000}\text{ gram}

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

67\ mg=67\times\dfrac{1}{1000}\ g\\\\=0.067\text{ g}

AND

0.6\ kg=0.6\times100=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.

16.47 is what percent of 61 show step by step
GalinKa [24]
Solution for 47 is what percent of 61:

47:61*100 =

(47*100):61 =

4700:61 = 77.05

Now we have: 47 is what percent of 61 = 77.05

Question: 47 is what percent of 61?

Percentage solution with steps:

Step 1: We make the assumption that 61 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x​.

Step 3: From step 1, it follows that $100\%=61$100%=61​.

Step 4: In the same vein, $x\%=47$x%=47​.

Step 5: This gives us a pair of simple equations:

$100\%=61(1)$100%=61(1)​.

$x\%=47(2)$x%=47(2)​.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{61}{47}$
100%
x%​=
61
47​​

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{47}{61}$
x%
100%​=
47
61​​

$\Rightarrow x=77.05\%$⇒x=77.05%​

Therefore, $47$47​ is $77.05\%$77.05%​ of $61$61​.
