Kiara tutors 20 hours each month at the library. She tutored for 2One-third hours the first week and 1.5 hours the second week. How many more hours does she need to tutor this month?

17.1 hrs

Step-by-step explanation:

If she tutored 2 1/3hours the first week and 1.5 hours the second week .

That’s 2 1/3 hrs + 1.5hrs

Change 2 1/3 to improper fraction. It becomes

7/5 = 1.4 hrs

1.4 hrs + 1.5 hrs = 2.9 hrs

So she’s tutored 2.9 hrs in the first 2 weeks

Hours remaining for her to tutor this week = hours she tutors every month - hours already done this month

That’s 20 hrs - 2.9 hrs

= 17.1 hrs

She has 17.1 hours more to tutor this month

20
