To divide a fraction, we multiply by its reciprocal.

Now, to do this by hand we look to see what can cancel out. Factors the same in top and bottom.
27 is 3*9 and 63 is 7*9 so we can divide both 27 and 63 by 9.

Now it should be clear, 35 is 5*7 so let's hit those.

6 is 3*2 So that's next.

And 8 is 4 * 2

Now we see that with 4*5=20, the whole equation simplifies to 1/1.
When we first set this up, we might have simply multiplied across, and seen 7560/7560=1, but this method I showed is the way to do it in most cases, where the canceling will stop, and you will be left with a good fraction.
