Question

As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular patients, you always mix Medication A with Medication B in the same proportion. Last week, your patient's doctor indicated that you should mix 90 milligrams of Medication A with 72 milligrams of Medication B. However this week, the doctor said to only use 8 milligrams of Medication B. How many milligrams of Medication A should be mixed this week?

Answer 1

Medication A mixed this week should be 10 milligrams.

We have,

Medications to be mixed in the proper proportions.

Last week's proportions;

Medication A = 90 milligrams

Medication B = 72 milligrams

This week's proportions;

Medication B = 8 milligrams

Let, Medication A = x milligrams

As we are instructed to mix in the proper proportions,

So,

According to the question,

90/72 = x/8

10/8 = x/8

⇒ x = 10 milligrams

Therefore, the Medication A mixed this week should be 10 milligrams.
