8 hours would be 33.3333333333...... % or 1/3.. 30% is 3/10
3/10 of 24 hours is 7.2 hours aslo 7 hours 12 minutes

No, it is not 8 hours. To get 30% of 24 hours, we need to convert 30% into a decimal form. To do that, we move the decimal point over two places to the left which is 0.3. Now we multiply.
24(0.3) = 7.2 hours

.30 x 24=7.2
Therefore, you are in school for exactly 7 hours and 20 minutes.
