Answer:
yes
Step-by-step explanation:
The maximum value of the function is 5/4.
Integer means a whole number , a number that is not fraction
Katie did not specifically said what numbers , the numbers can be fraction and it would not be called integer so that is Katie's error
7 7/8 - 3 1/4
7 7/8 = 6.125
3 1/4 = 0.75
so 6.125 - 0.75
= 5.375
as a mixed fraction the answer is 5 3/8
The answer will be 0.40 because 2 divided by 5 is 0.40
