The denominator for all of your answers is 9 (before you reduce to lowest terms)

Numerators as follows:

How many buttons with "8" on them are there in a set of buttons numbered 1 through 9?

How many buttons with even numbers are there in a set of buttons numbered 1 through 9?

How many buttons with numbers larger than 3 are in a set of buttons numbered 1 through 9? Note 3 is NOT larger than 3.
