    Answer: there are 24 girls.

    Step-by-step explanation:

    Let x represent the number of boys in fifth grade at lenape elemantary school.

    In fifth grade at lenape elemantary school,there are 4/7 as many girls as there are boys. This means that the number of girls in the school would be

    4/7 × x = 4x/7

    There are 66 students in fifth grade. This means that

    x + 4x/7 = 66

    Cross multiplying by 7, it becomes

    7x + 4x = 462

    11x = 462

    x = 462/11

    x = 42

    The number of girls would be

    66 – 42 = 24
