there are 24 hours in a day and scientists tell us that we should sleep for 3/8 of the day.how much time should we spend sleeping?

24*(3/8) =

3/8 means , 3 parts out of 8 parts of anything, in this case, full day or 24 hours. So divide 24 hours into eight equal parts. So 24/8 is 3. Now take three parts of it. That is 3 parts of 3 lots. The answer is 9 hours.

If you live for 100 years, how many years will you have spent sleeping?
