Question

A patient is to take 7 mL of amoxicillin 250 mg/5 mL. How many milligrams?

Answer 1

Explanation:

that means that in 5 ml there are 250mg.

and that means that in 1 ml there are 250/5 = 50 mg.

and now we can find out the mg in 7 ml (by multiplying everything by 7) :

7 ml = 50 × 7 = 350 mg
