Answer:
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
