Given:
15 mL of a solution contains 75 mg of medication.
To find:
How many mg of medication are in 60 mL of solution?
Solution:
We have,
Medication in 15 mL of a solution = 75 mg
Medication in 1 mL of a solution = [tex]\dfrac{75}{15}[/tex] mg
= [tex]5[/tex] mg
Medication in 60 mL of a solution = [tex]60\times 5[/tex] mg
= [tex]300[/tex] mg
Therefore, 60 mL of a solution contains 300 mg of medication.
