    'What is the ratio of students in Mrs. Murray's class who have an older brother to the number of students who does not have older brother?'

    Step-by-step explanation:

    In Mrs. Murray's class, the ratio of students in the class having an older brother to the total number of students is 1 : 3.

    So, we can say 3x is the number of total students in the class of Mrs. Murrays, and x students among them have an older brother.

    Hence, the number of students among all who do not have an older brother is (3x - x) = 2x

    Therefore, the question may be 'What is the ratio of students in Mrs. Murray's class who have an older brother to the number of students who does not have an older brother?'

    The answer is x : 2x = 1 : 2 (Answer)
