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]
