    Answer: 252 Boys, 168 Girls

    Step-by-step explanation:

    420 would be 100% of the school students.

    If you wanna find the number of girls, you need to divide 420/100 in order to get 1% and then multiply it by 40.

    So then you would get

    420/100 x 40 = 168

    Then in order to get the boys just subtract 168 from 420

    420 - 168 = 252
