Answers with steps as follows:

1. 5分之2小時 = 2/5 x 60 = 24分鐘

2. 9分之4天 = 4/9 x 24 = 10.6666... ( or 10 2/3 )小時

3. 12分之7分鐘 = 7/12 x 60 = 35秒

4. 3分之1天 = 1/3 x 60 x 24 = 480分鐘

5. 27分鐘 = 27/60 = 0.45 ( or 9/20 )小時

6. 3500秒 = 3500/60 = 58.3333... ( or 58 1/3 )分鐘

7. 15小時 = 15/24 = 0.625 ( or 5/8 )天

8. 1200秒 = 1200/3600 = 1/3小時

You can use them at once.

2. 9分之4天 = 4/9 x 24 = 10.6666... ( or 10 2/3 )小時
