    Answer:

    Girls = 319

    Step-by-step explanation:

    Given

    Boys: Girls = 15:11

    Required

    Find Girls, when Boys = 435

    Substitute 435 for Boys

    435: Girls = 15:11

    Express as fraction

    \frac{Girls}{435} = \frac{11}{15}

    Multiply through by 435

    435 * \frac{Girls}{435} = \frac{11}{15}* 435

    Girls = \frac{11}{15}* 435

    Girls = \frac{11* 435}{15}

    Girls = \frac{4785}{15}

    Girls = 319
