Question

8. A patient is told to take 12 1/2 grains (gr) of aspirin qd (every day). If the

aspirin tablets contain 5 gr each, how many tablets must the patient
take qd?

Answer 1

The patient must take
`2(1)/(2)\ tablets` per day

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

`(1)/(5) (tablet)/(gr) =(x)/(12.5) (tablets)/(gr) \\ \\x= 12.5/5\\ \\x=2.5\ tablets`

Convert to mixed number

`2.5=2(1)/(2)\ tablets`
