Step-by-step explanation:
Total time spent by students at school= 5 hours 30 minutes = 330 minutes.
Total break time= 15 minutes + 30 minutes= 45 minutes.
Ratio of the break time to the total time the students spend at school = 45:330.
=9:66.
9:66 is the required ratio.
Total time the students spend in school = 8am to 1:30pm = 5 hours 30 minutes
We know that,
1 hours = 60 minutes
5 hours = 5 × 60 = 300 minutes
∴ Total time = 300 minutes + 30 minutes = 330 minutes
Total break = 15 minutes + 30 minutes = 45 minutes
Ratio = 45 : 330
= 9 : 66 (Reduce to the lowest term)
Thus, the ratio of the break time to the total time the students spend in school is 9 : 66
