Question

If there are 5mg in 20ml of liquid medication, how many mg is in 4 ml of medication

Answer 1

Answer:

Explanation:

Given:

Amount of liquid medication = 5mg/20ml

To find the amount (mg) in 4 ml of medication, we use ratio:

Let x be the amount in mg for 4 ml of medication .

$\begin{gathered} \frac{5mg}{20ml}=\frac{x}{4ml} \\ \text{Simplify and rearrange} \\ x=\frac{5(4)}{20} \\ \text{Calculate} \\ x=\text{ 1mg} \end{gathered}$

Therefore, there is 1 mg in 4 ml of medication.
