SOLUTION: I don't understand how to simplify these answers. It says assume that no denominators are 0. Please show cancelling and factoring. 1. 11/12 � x/10 2. b^2/5 � b this one i

Question 486863: I don't understand how to simplify these answers. It says assume that no denominators are 0. Please show cancelling and factoring.
1. 11/12 � x/10
2. b^2/5 � b
this one i really don't understand.
3. y^2-49/z^2+z � y+7/z

thank you
