Kimi has a part-time job tutoring students in math for 40 hours each month. She will be tutoring one student for 1/4 of the allotted time this month and another student for 3/8 of the allotted time this month. How many hours of tutoring will she be able to provide to other students this month? Solve this multi-step real-world problem involving multiplication with fractions. Express the answer in simplest form.
Responses:
15 hours
21 1/4 hours
18 3/4 hours
25 hours
To find the number of hours Kimi will be able to provide to other students this month, we need to subtract the time she will spend tutoring the two students from the total amount of tutoring time.
Kimi will be tutoring one student for 1/4 of the allotted time, which is 1/4 x 40 = 10 hours.
And she will be tutoring another student for 3/8 of the allotted time, which is 3/8 x 40 = 15 hours.
Therefore, the total time she will spend tutoring these two students is 10 hours + 15 hours = 25 hours.
To find the remaining time available for tutoring other students, we can subtract this total tutoring time from the total allotted time of 40 hours.
Remaining time = 40 hours - 25 hours = 15 hours.
Therefore, Kimi will be able to provide 15 hours of tutoring to other students this month.
The correct response is 15 hours.
