Hello! I don’t know where is the mistake in the following sentences from a book (if there is any): Surveys show that 60% of the population sleeps between 7 and 8 hours a night. The other 40% sleep less, or more. Thank you.
It looks as though it makes sense..
As the 60% is referring to a finite number of the population, this technically should work, but as there are a plural number of people contained with in the 60%, it might work better as sleep. The sleep should usually be treated the same way for both
