    4/9 = x/2340

    Sorry, but that equation is not correct

    let the number of graduate students be 4x, let the number of undergrads be 9x
    so 4x+9x = 2340
    13x = 2340
    x = 180
    so number of undergraduates = 9x = 1620
    (graduate students = 4x = 720)

    notice 720:1620 = 4:9

    Thanks, Reiny.
