Question

Nicole finished her math assignment in 1/4 hours. Then she completed her chemistry assignment in 1/3 hours. How much more time did Nicole spend on her chemistry assignment?

Answer 1

Answer:

1/12 more

Step-by-step explanation:

Answer 2

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!
