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 50 milligrams of Medication A with 45 milligrams of Medication B. However this week, the doctor said to only use 36 milligrams of Medication B. How many milligrams of Medication A should be mixed this week?

Answer 1

40 mg

Explanation:

The ratio is 10:9 because 50:45 divided by 5 gives 10:9

if you divide 36/9 that gives you 4, then multiply your ratio by 4 to get 40:36.
