25xy/35x
= (25/35)(x/x)(y)
= (25 ÷ 5/35 ÷ 5)(1)(y)
= (5/7)(y)
= 5y/7

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
