8:00 a.m all the way until 2:00 p.m.
8:00 a.m. to 12:00 p.m is 4 hours.
12:00 p.m. to 2:00 p.m is 2 hours
8:00 a.m. to 2:00 p.m. is 6 hours.
6 hours out of a 24 hour day.
\(\frac{6}{24} =\frac{x}{100}\\\\\frac{1}{4} =\frac{x}{100}\\\\\sf{Cross~multiplying}\\\\100 = 4x\\\\\sf{Divide~4~on~both~sides\)
\(\boxed{\bf{x =25}}\)
The school holds classes for 25% of the 24-hour day.
