Thanks Aziz for that great explanation.

I just thought i would show how the cancelling is done in fraction form.

(I am playing with LaTex,  some of this is a bit new for me  )

 

9x5y44y×2y3x=93x54y442y×2y3x =3x4y42

Compare the cross or diagonal terms first.

9x^5*y^4 & 3x --> we can cross out the 3x entirely and change the 9x^5*y^4 into 3x^4*y^4 by dividing 9 by 3 and crossing out one x in x^5.

4y & 2y --> we can change 4y into 2(2y) and cross out the 2y.

Notice by crossing out the 3x and 2y, we are left with 1 / 1.

Thus, we have: 3x^4*y^4 / 2  * 1 / 1 -->

3x^4*y^4 / 2.
