Why there is an error? Is any part missing in the if statement?

I input this codes:

latex((4*n-1)/9-7/16*n)

\frac{n}{144}-\frac{1}{9}

This is not the output I expected.  I would like to obtain an expression similar to the one below.

\frac{4 n-1}{9}-\frac{7}{16}n

How can I achieve this, as Maple seems to have processed it internally.

Does maple over-understand the expression.

Good day,
 

1. Please I need your greatest help. Can anyone please help me to run the examples on the attached papers on Maple software?

 2. Also help me to plot the graphs along with the exact solution

 3. If possible with tables

 I tried but did not get the results as expected. I shall be very grateful if I can get assistance from you

 

Thanks
