    Answer:

    33

    Step-by-step explanation:

    To find the number of students, we must find out how many parts of a ratio are there.

    7+4 = 11 parts

    Then after finding the total parts, we know that the number of students must be a multiple of the total number of parts.

    11 x 3 = 33

    So, the total number of students is 33.

    4 x 3 = 12 Boys

    7 x 3 = 21 Girls.

    Thank you.
