Question

The doctor finally figures out what is wrong with you and prescribes a medicine that will return you to full health. The order is for 25mg of the medicine. The nurse walks in with a liquid and you ask to see the bottle. The bottle says 100mg of medicine per 15 ml of liquid. How many milliliters should she give you? (Round to hundredths place)

Answer 1

Hello Jessica.

To solve this, we need to convert units between milligrams and milliliters according to the ratio given.

Really, we're going to work with a series of fractions that compare quantities. It looks like this:

25 mg x 15 ml/100 mg = 3.75 ml
