The nurse administers a medication to a patient at 10 AM and 4 PM. The morning dose is 3/8 of an ounce and the afternoon dose is 3/7 of an ounce. The nurse has a one-ounce vial of medication. Is that enough medication? If not, how much more medication does the nurse need?
No, the nurse needs 11/56 of an ounce more.
No, the nurse needs 1/8 of an ounce more.
No, the nurse needs 1/7 of an ounce more.
Yes, the nurse has enough medication

To determine if the nurse has enough medication, we need to calculate the total amount of medication used and compare it to the one-ounce vial.
- Morning Dose:
ounce - Afternoon Dose:
ounce
First, find a common denominator to add these fractions. The least common multiple of 8 and 7 is 56.
Convert each fraction to have a denominator of 56:

Add these fractions:
+ 
= 
So, the total amount of medication used is 
ounce.

Since 
ounce is needed more to make up for the used amount, the nurse needs: 
of an ounce more.
Therefore, the correct answer is:
