We have to administer 1.5 mg of medication in tablets that have 0.5 mg per tablet.
We can calculate n, the numbers of tablet needed as the quotient between the drug needed and the drug per tablet:
[tex]\begin{gathered} n=\frac{D}{d} \\ n=\frac{1.5\text{ mg}}{\frac{0.5\text{ mg}}{1\text{ tablet}}}=\frac{1.5}{0.5}\text{ tablet}=3\text{ tablets} \end{gathered}[/tex]Answer: 3 tablets.
