The answer is: 1.187 tablets each time (twice a day)
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:
[tex]1 Pound=0.45Kg[/tex]
So,
[tex]211Pounds*\frac{0.45Kg}{1Pound}= 94.95Kg=95Kg[/tex]
A weight of 95 Kg, means 4.75 times more than the given information of 0.5 table a day, per 20 Kg
[tex]\frac{95Kg}{20Kg}=4.75[/tex]
Then,
[tex]4.75*(0.5)=2.375[/tex]
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!
