Answer 1

Answer:

1/10

Step-by-step explanation:

Lunch interval = 30 minutes = 0.5 hours

Class is up to 3:30 PM = 15:30 PM

So total time of the class periods = (15:30 - 10:00) - 30 minutes of lunch interval = 5 hours

Therefore the ratio of lunch interval to total time of the class periods = 0.5 / 5 = 1 / 10
