Question

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

Answer 1

Step-by-step 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} (5mg)/(20ml)=(x)/(4ml) \\ \text{Simplify and rearrange} \\ x=(5(4))/(20) \\ \text{Calculate} \\ x=\text{ 1mg} \end{gathered}`

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