To divide by a fraction, flip the second fraction upside down.
So you get 8/9 * 15/11.
Now just multiply top and bottom:
120/99.
Both of those are multiples of 3, so we can divide top and bottom by 3:
40/33.
Thats simplest form.

Division is multiplication by the reciprocal. The reciprocal of 11/15 is 15/11 so
(8/9)/(11/15) = (8/9)*(15/11)
mult num and denoms
= 8*15/(9*11) = 120/99 , to reduce notice that both are divisible by 3
= 40/33 , no common factors so that's it.

8/9 / 11/15
=8/9 X15/11
=40/33
=1 7/33

(8/9)/(11/15) = (8/9)(15/11) = 120/99 = 40/33 = 1 7/33

to divide fractions:
(top/bottom) / (top/bottom)
is really
(top/bottom) * (bottom/top)
you inverse the bottom (flip it upside down)
and then multiply.
(8/9) / (11/15)
(8/9) * (15/11)
Let's reduce a little before multiplying.
Pull otu a common factor of 3 from the 9 and the 15
(8/3) * (5/11)
40/33
