Question

Harriet’s band practice lasts 2.95 hours. If they have been practicing for 1 3/8 hours, how many hours remain?

a. 1.57 hours

b. 1.32 hours

c. 2.10 hours

d. 1.42 hours

Answer 1

To find out how many hours remain, subtract the amount of time already practiced from the total practice time. Harriet's band practice lasts 2.95 hours, and they have already practiced for 1 3/8 hours. To subtract a mixed number, convert it to an improper fraction. 1 3/8 is equal to 11/8 hours. So, the calculation is: 2.95 - 1.375 = 1.575. Therefore, there are approximately 1.57 hours remaining.

Step-by-step explanation:

To find out how many hours remain, subtract the amount of time already practiced from the total practice time.
