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
The Correct Answer is A
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:

= 
- For
:
= 
= 
Add these fractions:
+ 
= 
So, the total amount of medication used is 
ounce.
The vial contains 1 ounce. The amount of medication remaining in the vial is:

= 
− 
= 
Since 
ounce is needed more to make up for the used amount, the nurse needs: 
of an ounce more.
Therefore, the correct answer is:
No, the nurse needs
