Answer:
1 tablet and a half.
Explanation:
1 mg is equivalent to 1/60gr
or
1 gr is equivalent to 60 mg.
Since you need to give 1/4 gr of morphine sulfate, you need to give 1/4 of 60mg. If you will calculate that, you will need to give 15 mg of morphine sulfate. Since the tablets come in 10 mg, you will need to give 1 tablet and a half.
You can also compute it this way:
[tex]\dfrac{1}{4}gr\times \dfrac{60mg}{1gr} = \dfrac{60mg}{4}=15mg[/tex]
[tex]15mg\times \dfrac{1 tablet}{10mg} = 1.5 tablets[/tex]
