Question

a medication prescription states 1/4 tablet twice a day per 20kg the peson weight is 211 pounds. how many tablets should be taken each time?

Answer 1

Hello!

The answer is: 1.187 tablets each time (twice a day)

Why?

From the statement we know that 0.25 tablet (1/4) should be taken twice a day per 20 kg, it makes 0.5 table a day, per 20 kg.

First, we need to convert the given weight unit (pounds) to kg:

$1 Pound=0.45Kg$

So,

$211Pounds*\frac{0.45Kg}{1Pound}= 94.95Kg=95Kg$

A weight of 95 Kg, means 4.75 times more than the given information of 0.5 table a day, per 20 Kg

$\frac{95Kg}{20Kg}=4.75$

Then,

$4.75*(0.5)=2.375$

So,

For a weight of 95 Kg,  2.375  tablets should be taken a day, or 1.187  tablets each time.

Have a nice day!
