Answer:
1/12 more
Step-by-step explanation:
1/3 of an hour (60 minutes) is 20.
1/4 of an hour is 15.
Subtract and receive 5.
So Nicole spent 5 more minutes on her chemistry assignment.
Another way to tackle this problem is to subtract the fractions after finding their common denominator (12)
4/12-3/12=1/12
1/12 of an hour is 5.
I used 2 different methods and I had the exact same answer. Hope it's helpful!
