Some doubts about symbolic equations in Wolfram Mathematica

I need to perform the following operations using Wolfram Mathematica.

I have these equations:

$$a b = c+d+e$$

$$frac{d}{f}=g h + i$$

$$k=frac{a}{c}$$

I need to obtain $k$ as a function of: $a,b,c,e,f,g,h,i$

Then I need to put the expression $k$ in the form: $$k= frac{1}{b}+frac{(f(g h + i))+e)}{(b c)}$$

I made this code:

In: Solve [a b == c + d + e, a]

Out: {{a -> (c + d + e)/b}}

In: Solve[d/f == g h + i, d]

Out: {{d -> f (g h + i)}}

In: k = a/c /. a -> (c + d + e)/b

Out: (c + d + e)/(b c)

In:  k = k /. d -> f (g h + i) 

Out: (c + e + f (g h + i))/(b c)

In: Simplify[k]

Out: (c + e + f g h + f i)/(b c)

I have 2 questions:

1. Is there a simpler way to perform that task? For example, using others commands.

2. Is there a way to obtain the expression of k in the form $k= frac{1}{b}+frac{(f(g h + i))+e)}{(b c)}$ ?

Clear["Global`*"]

eqns = {a*b == c + d + e, d/f == g*h + i, k == a/c};

sol = Solve[eqns, k, {a, d}][[1]] // Simplify

(* {k -> (c + e + f g h + f i)/(b c)} *)

expr = 1/b + j/(b*c);

sol2 = {k -> expr} /. Solve[(k /. sol) == expr, j][[1]]

(* {k -> 1/b + (e + f g h + f i)/(b c)} *)

(k /. sol) == (k /. sol2) // Simplify

(* True *)
