What's the fraction of it

Hello, unit 1 is the number of the whole class, set the number of the whole class as X, then the number of boys is 7x out of 12, and that of girls is 5x out of 12. (because the number of boys in the class is reduced by 7 out of 12) 7 / 12x-5 / 12x = 2 / 12x = 1 / 6, so boys are 1 / 6 more than girls. Girls are 1 / 6 less than boys, and girls account for boys = (1-7 / 12) / / 7 / 12 = 5 / 7
