In a recent year, 22 percent of email users said they spend less time using email because of spam. what fraction of email users is this

Remember, percent is always out of 100. If you have 22%, you have 22 people per every 100 people, or, 22/100. 

22/100 is the incomplete answer because it needs to be simplified. If you divide both numbers by two you get 11/50 which is the lowest fraction you can have because 11 is a prime number.
