Question

If there are 2mg in every ml of this medication, how many mg is there in 20ml of this medication

Answer 1

From the information given, we can write the conversion ratio as,

`(2mg)/(1ml)`

We want to know how many mg (let it be "x") is there in 20 ml.

We can setup a proportion as shown below:

`(2mg)/(1ml)=(x)/(20ml)`

Solving for "x",

`\begin{gathered} (2mg)/(1ml)=(x)/(20ml) \\ x*1=2*20 \\ x=40mg \end{gathered}`Answer40 mg
