<h2>Hello!</h2>
The answer is: 1.187 tablets each time (twice a day)
<h2>Why?</h2>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:
So,
A weight of 95 Kg, means 4.75 times more than the given information of 0.5 table a day, per 20 Kg
Then,
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!
