i want to know if division distributive over addition??? and why?? or does it depend on the example??

The distributive property works for multiplication over addition orsubtraction:

a(b - c) = ab - ac
(a - b)c = ac - bc

But you can only distribute division over addition (or subtraction) in
one direction:

a/(b + c) = a/b + a/c is false
(a + b)/c = a/c + b/c is true
