Answer:
The patient must take [tex]2\frac{1}{2}\ tablets[/tex] per day
Step-by-step explanation:
we know that
12 1/2 grains (gr) of aspirin is equal to 12.5 grains
using proportion
Let
x -----> the number of aspirin tablets
[tex]\frac{1}{5} \frac{tablet}{gr} =\frac{x}{12.5} \frac{tablets}{gr} \\ \\x= 12.5/5\\ \\x=2.5\ tablets[/tex]
Convert to mixed number
[tex]2.5=2\frac{1}{2}\ tablets[/tex]
