Answer 2

Answer:

1 13/30

Step-by-step explanation:

Harry spell casting class lasts for 2 5/6 hours each day

= Convert it into a mixed fraction:-

= 2 5/6 = 17/6

And Today, he has been in the class for 1 2/5 of an hour so far.

= Convert it into a mixed fraction:-

= 1 2/5 = 7/5

Now, how much time is left?

= 17/6 - 7/5

Denominators are not equal, so make it equal.

For that, Find the LCM.

= LCM of 5 and 6 = 30

So, 17/6 = 17 x 5 / 6 x 5 = 85/30

Therefore, 7/5 = 7 x 6 / 5 x 6 = 42/30

= We have to find how much time is left, =  85/30 - 42/30

                                                                      = 43/30 (in improper fraction)

                                                                      = 1 13/30 (in mixed fraction)
