Question

Harry's spell casting class lasts for 11/6 hours each day. Today, he has been in the class for 7/5 of an hour so far. How much more time is left in the class?

Answer 1

Answer:

13/30 hours

Step-by-step explanation:

11/6 - 7/5 = 55/30 - 42/30 = 13/30

Answer 2

Answer: 1 13/30 hrs left

Step-by-step explanation:

his class lasts 2 5/6 hrs...and he has already been in there for 1 2/5 hr

so the time he has left can be found by subtracting the time he has been there from the total time of the class

2 5/6 - 1 2/5....

(2 - 1) = 1 : (5/6 - 2/5 = 25/30 - 12/30 = 13/30)

so he has 1 13/30 hrs left
