    "2/9 of the students are absent" so 1 - (2/9) = (9/9) - (2/9) = 7/9 of the students are present agreed?

    "1/4 of those in school have gone to the library" (1/4) of (7/9) = (1/4)*(7/9) = 7/36

    look through the list of choices. There is only one number that when multiplied by 7/36, the result is a whole number
