First part:
1. Find the total amount of marks without the 8 marks.
2. Use the total to minus the marks (without 8 marks)
3. Remaining is the total marks of 8 marks
4. The total marks of 8 divided by 8 is the number of students that received 8 marks.
Second part:
1. 24 hours = 100%
2. Since half is 50%, meal and work is 50%.
3. 50% - 25% = 25% (travel + leisure)
4. 25% - 20% (travel) = 5% (leisure)
5. Use the 100% to find 1%
6. Multiply 1% to find 5% which is leisure to get the answer
