You start with the greater number when adding on a number line simply for convenience.
Put it this way:
Would you rather add more to a small number or add less to a large number?
Naturally people would choose to add less to a large number because that way you do not have to do so much work. So, you would start with the greater number when adding on a number line.
9/8 + 9/4 = 27/8.
Multiply 9/4 by 2.
9/4 • 2 = 18/8
Then, add the fractions.
9/8 + 18/8 = 27/8
Simplify 27/8.
27/8 = 3 3/8
