Answer:

The estimated difference is 11.

Step-by-step explanation:

[tex]18\frac{9}{11}[/tex] in simplified form is 18.81. This when rounded to whole number becomes 19.

Similarly, [tex]8\frac{3}{8}[/tex] in simplified form is 8.375 and when rounded to nearest whole number, it becomes 8.

Now, the difference will be :

[tex]19-8=11[/tex]

So, the estimated difference is 11.
