First you want to try to factor everything out.
25xy/35x
[(5)(5)(x)(y)] / [(5)(7)(x)]
~You can cancel out the 5 and x on the top and bottom because it's like like saying 2/2 = 1~
5y/7
You can cancel the x's in that expression so you get:
25y/35
But you can still cancel it down further because 35 and 25 are divisibe by 5:
5y/7
25xy / 35x
5(5xy) / 7(5x)
cancel the 5x:
5y/7
25 divided by 35
x into x = 1
y not divided by anything
25y/35
5y/7
5/7y
