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 sleepi ng?

The answer would be 9 hours.
An easy way to do this would be to convert the fraction into a decimal and multiply. You can use a calculator for this. Convert 3/8 into a decimal, which will be 0.375. Now multiply 24 * 0.375 = 9. So doctors say you should spend 9 hours sleeping.
