    Answer is 25/56

    Step-by-step explanation:

    Given that

    Katie and her brother are both writing a report. Katie write 7/8 of her report and her brother wrote 3/7 of his report

    TO compare these two fractions we have to make both of them have the same denominator.

    We find that as such the two fractions have denominators as 7 and 8 and hence Least common multiple is 56

    LEt us make equivalent fractions

    7/8 = 49/56

    3/7=24/56

    Difference i. e. Katie wrote more than her brother = 49/56-24/56

    =25/56
