    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
