5%2F%28y%2B1%2925%2F%287y%2B7%29

Invert the second fraction and change the division to multiplication:

5%2F%28y%2B1%29%287y%2B7%29%2F25

Factor 7 out of the numerator on the right:

5%2F%28y%2B1%29%287%28y%2B1%29%29%2F25

Cancel the (y+1)'s

5%2F%28cross%28y%2B1%29%29%287%28cross%28y%2B1%29%29%29%2F25

Also cancel the 5 into the 25, getting 5

cross%285%29%2F%28cross%28y%2B1%29%29%287%28cross%28y%2B1%29%29%29%2F%28cross%2825%29%5B5%5D%29%29

7%2F5
