Answer: The number of people reading interesting fairy tales = 42 * 3/6 = 2 1 (person), interesting language = 42 * 2/6 = 14 (person), children's literature and art = 42 *16 = 7 (person), depending on mathematics.
There is another solution to this problem. More people watch math fairy tales than interesting Chinese =42*(3/6-2/6)=42* 1/6=7 (people), and more people watch children's literature and art = 42 * (3/6- 1/6) = 42 *.
