First, we're going to find the LCD, Least Common Denominator, of both fractions.
9- 9, 18, 27, 36.
18- 18, 36, 54, 72.

As you can see, 18 is the LCD of both fractions.

Then we're going to multiply both the fractions to get the denominator the same.

(8)/(9) x 2 =
(16)/(18)

(13)/(18) x 1 =
(13)/(18)

*Remember, whatever you do to the top, you do to the bottom.*
**Do not follow the rule above if you are not making the denominators the same.**

Now we're going to subtract
(16)/(18) by
(13)/(18)

(16)/(18) -
(13)/(18) =
(3)/(18)

Then, we're going to simplify it.

(3)/(18) / 3 =
(1)/(6)

This is how we get our answer,
(1)/(6)

Our final answer is
(1)/(6)

Hope this helps!~
