Final answer:
To find the fraction of time left for doing other things, subtract the time spent in bed, lessons, and homework from the total time in a week. The fraction of time left is 32/50.
Step-by-step explanation:
To find the fraction of time left for doing other things, we need to subtract the time spent in bed, lessons, and homework from the total time in a week. Let's assume the total time in a week is 100 units.
- Time in bed = 24 units
- Time in lessons = 5 units
- Time doing homework = 7 units
The fraction of time left for doing other things = Total time - Time in bed - Time in lessons - Time doing homework = 100 - 24 - 5 - 7 = 64 units. Therefore, the fraction of time left for doing other things is 64/100 or 32/50.
