Answer:
The dosage has 1.2ml
Explanation:
This problem can be solved as a rule of three problem.
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.
Unit conversion problems, like this one, is an example of a direct relationship between measures.
First step: The first step is the conversion from mcg to mg.
The bottle has 60 mcg. How much is this in ml? 1 mcg has 0.001mg. So:
1 mcg - 0.001mg
60mcg - x mg
x = 60*0.001
x = 0.06mg
Final step: The bottle of elixir contains 0.05 mg per 1 ml. Calculate the dosage in ml.
The dosage has 0.06 mg, so:
0.05mg - 1 ml
0.06mg - xml
0.05x = 0.06
x = 1.2ml
The dosage has 1.2ml
