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](https://img.qammunity.org/2020/formulas/mathematics/high-school/jn1a6ad46z0eeq8aui569lk5vu67qgggxd.png)
So,
![211Pounds*(0.45Kg)/(1Pound)= 94.95Kg=95Kg](https://img.qammunity.org/2020/formulas/mathematics/high-school/mmyx0zju79q9d1mbd55likervzs118m1rx.png)
A weight of 95 Kg, means 4.75 times more than the given information of 0.5 table a day, per 20 Kg
![(95Kg)/(20Kg)=4.75](https://img.qammunity.org/2020/formulas/mathematics/high-school/4rsj7s9x286vrjjp2hlzanb9gf1w4ebw2h.png)
Then,
![4.75*(0.5)=2.375](https://img.qammunity.org/2020/formulas/mathematics/high-school/9q2c322kvo9de8b8gvs8tw2mtjckfxfr32.png)
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!
