Answer:
25%
Step-by-step explanation:
So first we need to find out how many hours the school has class. Its 4 hours from 8 to noon, then another 2 from noon to 2. This means the school has class 6 hours a day.
Now we need to figure out the percent. we need to have hours of school over total hours or 6/24
6/24
we can simplify this by dividing both sides by 6
(6/6)/(24/6)=1/4
1/4 is 25%
The school holds class for 25% of the day
