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 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.

To solve the problem, we need to find the total amount of time Kimi will spend tutoring the two students and subtract that from the total amount of time she has available for tutoring.
Kimi has 40 hours available for tutoring each month.
For the first student, she will tutor them for 1/4 of the time. To find out how many hours that is, we multiply 40 by 1/4:
40 * 1/4 = 10
So, Kimi will tutor the first student for 10 hours.
For the second student, she will tutor them for 3/8 of the time. To find out how many hours that is, we multiply 40 by 3/8:
40 * 3/8 = 120/8 = 15
So, Kimi will tutor the second student for 15 hours.
To find out how many hours of tutoring Kimi will be able to provide to other students, we subtract the time she will spend tutoring the two students from the total available time:
40 - 10 - 15 = 15
Therefore, Kimi will be able to provide 15 hours of tutoring to other students this month.
The answer is 15.
