It means for every 38 students , 12 of them are boys . Lets say you and your friend won \$ 50 for some reason , so its only fair both of you get \$25 each . So you get 1/2 of the \$50 . Or if there are 4 person who won the \$ 50 , so each got 1/4 of \$50 or 25 percent of the money .

Well , i thought u meant sth else . Ok , it's correct , then multiply by 100% would give 31.6%

31.5789473 , rounding off to one decimal place gives 31.6
