    Step-by-step explanation:

    The ratio of boys to girls is 3 to 7.

    We don't know the number of boys or girls. The number of boys and the number of girls are multiples of 3 and 7, respectively. Since they are in the ratio of 3 to 7, then by multiplying both 3 and 7 by the same number, you will get the number of boys and the number of girls. We need to find that number. Call that number x.

    The ratio of boys to girls is:

    3x to 7x

    There are 3x boys and 7x girls.

    The number of girls is 200 more than the number of boys.

    7x = 3x + 200

    Subtract 3x from both sides.

    4x = 200

    Divide both sides by 4.

    x = 50

    The number of boys is 3x, so

    3x = 3 (50) = 150
