    Answer: 1/7

    Step-by-step explanation:

    Total questions answered = 49

    Harry correct answers = 42

    Harry wrong answers = (49 - 42) = 7

    Thus, the only fraction of wrong answers = (Number of wrong answers / Total number of questions answered)

    i. e 7/49

    = 1/7

    Thus, harry answered 1/7 of the 49 questions wrongly.
