A school holds classes from 8:00 a.m -2:00 p.m. For what percent of a 24- hour day does this school hold classes?

kati45 [8]

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.
